The answer is: x3+64=(x+4)(x2−4x+16) . It’s easy if we remember the formula of sum of cubes, that says: x3+y3=(x+y)(x2−xy+y2) . In this case 64=43 .
Is x 2 6x 9 a perfect square trinomial?
The trinomial x2 + 6x + 9 is a perfect square trinomial. Let’s factor this trinomial using the methods you have already seen. Factor x2 + 6x + 9. Rewrite 6x as 3x + 3x, as 3 • 3 = 9, the last term, and 3 + 3 = 6, the middle term.
