x%5E2+%2B+6x=+16
x%5E2+%2B+6x-16=0...replace 6x with -2x%2B8x
x%5E2+-2x%2B+8x-16=0...group first two terms and second two terms together
%28x%5E2+-2x%29%2B+%288x-16%29=0
x%28x+-2%29%2B+8%28x-2%29=0
%28x%2B+8%29%28x-2%29=0

Hi,

 X^2 + 6X = 16

 X^2 + 6X - 16 = 0

factoring

(X+8)(X-2) = 0   

(X+8) = 0, X = -8

(X-2) = 0, X = 2 

X is -8 or  2
