Answer:
x = -8 and x = 4
Step-by-step explanation:
x(x+4) = 32
or, x^2 + 4x = 32
or, x^2 + 4x - 32 = 0
or, x^2 + 8x - 4x - 32 = 0
or, x ( x + 8 ) - 4 ( x + 8 )
or, (x-4) (x+8)
x - 4 = 0
or, x = 4
x + 8
or, x = -8

Answer:
x(x+4) =32
x²+4x=32
x²+4x-32=0
x²+(8-4) x-32=0
x²+8x-4x-32=0
x(x+8) -4(+8) =0
(x+8) (x-4) =0
:. (x+8) =0 or, (x-4) =0
x=-8 x=4
