sorry i am not sure but i dont think it has an answer If this equation is: x^2 - 36 = 5x, then:
x^2 - 36 = 5x subtract 5x to both sides;
x^2 - 5x - 36 = 0 Factor; (x + 4)(x - 9) = 0
x + 4 = 0 or x - 9 = 0
x = -4 or x = 9

When factored it is: (x-9)(x+4)
Assuming that x2 is x squared: (x - 9)(x + 4)
. x + 4
(x - 2)(x - 3)
x2-5x+4 = (x-1)(x-4) when factord
