Please help me

Answer 1

Answer:

a

Step-by-step 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

Answer:

option a is correct.

Step-by-step 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
