Answer Let the sides of the two squares be x m and y m. On dividing x 3 — 3 x 2 + x + 2 by a polynomial g x , the quotient and remainder were x — 2 and -2 x + 4, respectively. Here, both the roots are equal. It explains about the feasible and infeasible regions that are also known as bounded and unbounded. Had he got 3 marks more in Mathematics and 4 marks less in Science, the product of his marks, would have been 180. Apart from that, the detailed solutions also help the students to learn the class 6 maths concepts in a better and more effective way. Is it possible to design a rectangular park of perimeter 80 metres and area 400 m 2.

When 18 is added to the number, the digits interchanged their places. Find her marks in the two subjects. Hence, the given equation is quadratic equation. If the hypotenuse is 13 cm, find the other two sides. Find two consecutive positive integers, sum of whose squares is 365. These will be intersecting each other at point R. You will see how continuity and differentiability based on chain rule, composite functions, implicit functions, logarthmic functions and exponential functions.

You will learn the theorem of calculus with the help of some problems and their solutions. We need to find the integers. Four years ago, the product of their ages in years was 48. Find two consecutive positive integers, sum of whose squares is 365. Find the nature of the roots of the following quadratic equations. How much time you are spending daily on the studies. In this chapter we will see the solutions for a applications of determinants.

Therefore, their perimeter will be 4 x and 4 y respectively and their areas will be x 2 and y 2 respectively. Let the point of intersection be M. Hence, the given equation is not a quadratic equation. All Quadratic Equations Exercise Questions with Solutions to help you to revise complete Syllabus and Score More marks. Therefore, their perimeter will be 4 x and 4 y respectively and their areas will be x 2 and y 2 respectively. Therefore, it is possible to design a rectangular grove. It is highly recommended that you practice thoroughly and learn properly all of the given solutions here.

A train travels 360 km at a uniform speed. Find the speed of the stream. Mark a point A interior and a point B in its exterior. Here you will going to learn about the properties of probability. We recommend you to take some tiny small breaks in between the learning sessions. As vertex A is 6.

Find the speed of the stream. The square of the smaller number is 8 times the larger number. Find the roots of the quadratic equations given in Q. Hence, the given equation is quadratic equation. Hence, the Solutions are provided here which can be downloaded and checked at any time. Therefore, their perimeter will be 4 x and 4 y respectively and their areas will be x 2 and y 2 respectively.

Our professionals has invested their dedicated efforts to get the best results. Find the time in which each tap can separately fill the tank. This line will meet touch the previously drawn ray from A at point N. These breaks can be eating some fruits or drinking tea, etc. Therefore, while taking L and I as centres, draw arcs of 4. These are i Factor Method ii Completing the square method and iii Using the Quadratic Formula.

The cost of production of each toy in rupees was found to be 55 minus the number of toys produced in a day. By taking radius as 6cm and 5cm, draw arcs from point H and A respectively. Since age cannot be in negative. Eight years hence, the age of the man will be 4 years more than three times the age of his son. The chapter concludes with summarizing points that helps to learn the chapter at a glance.

Therefore, while taking D and L as centres, draw arcs of 10 cm radius and 7. In the textbook, there are several activities and exercises for the students to help them be engaged with learning and have a better understanding of the concepts. Measurements of the adjacent sides are 6 cm and 3 cm long. However, age cannot be negative. Introduction to Quadratic Equations, Quadratic Equations in detail, Solution of a Quadratic Equation by Factorisation, Solution of a Quadratic Equation by Completing the Square and Nature of Roots are the main topics studied in this chapter. Hence, the given equation is quadratic equation.
