Question

check weather (x+3) is a factor of p(x) =x2-9

Answer 1

Answer:

▶Here's your answer

⏩By factor Theorem...

➡x+3=0

➡x =-3

Step-by-step explanation:

$p(x) = {x}^{2} - 9 \\ \\ p( - 3) = { - 3}^{2} - 9 \\ \\ = 9 - 9 = 0$

▶Yes, It is the factor of the given...equation

Hope it helps ✌

Answer 2

Answer:

$x + 3 = 0 \\ x = - 3 \\ p(x) = {x}^{2} - 9 \\ p ( - 3) =( { - 3})^{2} - 9 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 9 - 9 = 0$
