Question

7. The sum of two polynomials is 5X2
+ 3x - 1. If one of them is 3x 2 - 2x + 7, find the other


​

Answer 1

Answer:

Correct option is

A

8x

2

−7x−4

Given polynomials are 3x

2

−5x+2 and 5x

2

−2x−6

The sum of the given polynomials is given by:

(3x

2

−5x+2)+(5x

2

−2x−6)

=(3x

2

+5x

2

)+(−5x−2x)+(2−6)

=8x

2

−7x−4
