Question

Factor by grouping. x^2 – 6x + 5x – 30

Answer 1

(x-6)(x+5)

Answer 2

factor an x out of the first 2 terms
factor a 5 out of 2nd 2 terms
x^2-6x+5x-30
x(x-6)+5(x-6)
now factor an (x-6) out of both terms
(x-6)(x+5)

Answer 3

= x² + (-6x+5x) - 30
= x² - x - 30 (find two number multiply equals -30 but add to -1) This case -6,5
= (x + 5)(x - 6)
