25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
x2 + 9x2 = 10x2
x(x2+5x+6)
lcm(4x, 5x) = 20x
No.
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)
x2 + 9x2 = 10x2
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.
