factorsation
(x² +6x-16)​

Answer 1

Answer:

x^2+8x-2x-16

Step-by-step explanation:

x(x+8)-2(x+8)

(x-2)(x+8)

x=2 or x=-8

Answer 2

Answer:

${x}^{2} + 6x - 16 \\ = {x}^{2} +(8 - 2)x - 16 \\ = {x}^{2} + 8x - 2x - 16 \\ = x(x + 8) - 2(x + 8) \\ = (x + 8)(x - 2) \\ therefore \: x = - 8 \: or \: x = 2$
