5(x2 + x + 1)
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
(5x - 2)(x - 5)
5(x^2 + 9)
5
x2 + 5x + not really sure what that extra plus is for... this is the most you can factor it... x(x + 5)
5x^2(4x - 5)(5x + 11)
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
1. If the question is only to factor this expression:x^2 + 5x = x(x + 5)2. If the question is to solve the equation x^2 + 5x = 0:x^2 + 5x = 0 factor it;x(x + 5) = 0x = 0 orx + 5 =0 subtract 5 to both sides;x = - 5
It is: 5(x^2 -16)
2x2 + 5x = x*(2x + 5)
-6 = 3 x -2 13 = 5 x 3 - 2 → 5x² + 13x - 6 = (5x - 2)(x + 3)
f(x) = 3x2 + 5x + 2fprime(x) = 6x + 5
