=3x * * * * * The correct answer is: x2 + 7x + 12 = (x + 3)(x + 4).
(x + 10)(x - 3)
(x - y + 7)(x + y)
You find two numbers whose sum is -7 and product is +10. x2 - 7x + 10 = (x - 2)*(x - 5)
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
Easy, peasy! x2 + 7x - 144 = (x + 16)(x - 9).
(x2 + 7x - 18) = (x + 9)(x - 2)
x2 + 7x + 6 = (x + 6) (x + 1)

(x - 7)(x2 + 7x + 49)
x2 + 7x - 56 cannot be factorised.
