x + 4
(x2 plus 40) (x minus 1)
x2 + 8x + 15 = (x + 3) (x + 5).
x2 + 9 + 20 = x2 + 29, and can not be factored.I assume though that you mis-wrote your question, and what you in fact want to ask is how to factor x2 + 9x + 20.In that case, the answer is (x + 4)(x + 5).
=3x * * * * * The correct answer is: x2 + 7x + 12 = (x + 3)(x + 4).
