Question

 If (x+8)²-5=31 than roots are

A》-2,14

B》-2,-14

C》2,14

D》2,-14​

Answer 1

OPTiON B → -2 , -14

Step-by-step explanation:

(x + 8)² - 5 = 31

x² + 64 + 16x - 5 = 31

x² + 16x + 64 - 36 = 0

x² + 16x + 28 = 0

x² + 14x + 2x + 28 = 0

x(x + 14) + 2(x + 14) = 0

(x + 14) (x + 2) = 0

x = -2 or -14
