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:
option a is correct.
Step-by-step explanation:
To find the sum of given two expressions,we add coefficients of [tex]x^{2}[/tex],[tex]x[/tex] and constant
[tex](4+2)x^{2} +(-5+7)x+(3-8)[/tex]
[tex](6)x^{2} +(2)x+(-5)[/tex]
[tex]6x^{2} +2x-5[/tex] which is the correct answer
