25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
x(x2+5x+6)
No.
Well, darling, the Least Common Multiple (LCM) of 4x and 5x is simply 20x. You see, 4x and 5x are both factors of 20x, making it the smallest multiple they both share. So, there you have it, sweet pea, 20x is the LCM of those two little troublemakers.

5(x + 3)(x + 1)
5x2 + 20x = 5x (x + 4)
5x^2 + 20x
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
20x+7=5x+10 15x=3 3/15=.2 x=.2
4(5x + 3) - 9 = 20x + 3
5x(x^4+7x+4)
5x(3x+4)
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
3x - 7 = 5x + 13-2x = 20x = -10
Assuming you mean x squared plus 5x squared... the answer is 6x squared.
