Question

solve using factorization method
(x-8) (x+4) = 13

Answer 1

(x-8) (x+4)=13
x^2+4x-8x-32=13
x^2-4x-45
x^2-9x+5x-45
x(x-9) 5(x-9)
(x+5) (x-9)
x=-5
x=9

Answer 2

First, expand the brackets to obtain x2−4x−32=13x2−4x−32=13. Subtract 13 from both sides to obtain x2−4x−45=0x2−4x−45=0. The left hand can be factorised as (x−9)(x+5)(x−9)(x+5). Now we equate both factors to z
