Question

p(x) =x square +8x+9 (x=3,x
= -4)​

Answer 1

Answer:

42, -7

$p(x) = {x}^{2} +8x+9 \\ if \: x = 3 \: then \\ = > p(3) = {3}^{2} +8(3)+9 \\ = 9 + 24 + 9 \\ = > 42$

------------------------------------------------------------

$p(x) = {x}^{2} +8x+9 \\ if \: x = - 4 \\ = > p( - 4) = { (- 4)}^{2} +8( - 4)+9 \\ = 16 - 32 + 9 \\ = > - 7$
