A.
2 and –16

B.
–6 and 6

C.
–2 and 16

D.
–9 and 8

Answer 1

hi,
factorize the expression first..
x2 – 14x – 32 = 0
x^2 - 16x + 2x -32 =0
x( x - 16 ) +2 ( x -16) = 0
(x + 2)( x -16) = 0

did u get it so far ??

Answer 2

yes ok

Answer 3

so... now we got
(x + 2)( x -16) = 0
which means
either
(x + 2) = 0 or ( x -16) = 0
from that we can say...
x = -2 or x = 16

I think now u have ur answers lol

Answer 4

ok thnx
