Question

Please help me

add.

4x^2-5x+3
+ 2x^2+7x-8


a. 6x^2+2x-5

b. 6x^2+2x+11

c. 6x^2-2x+5

d. 6x^2+12x-5

Answer 1

a

Explanation:

To sum the 2 expressions collect like terms

4x² - 5x + 3 + 2x² + 7x - 8

= (4x² + 2x² ) + (- 5x + 7x ) + (3 - 8 )

= 6x² + 2x + (- 5)

=6x² + 2x - 5 → a

Answer 2

option a is correct.

Explanation:

To find the sum of given two expressions,we add coefficients of
`x^(2)`,
`x` and constant

`(4+2)x^(2) +(-5+7)x+(3-8)`

`(6)x^(2) +(2)x+(-5)`

`6x^(2) +2x-5` which is the correct answer
