9x2 + 12x + 4 = 9x2 + 6x + 6x + 4 = 3x(3x + 2) + 2(3x + 2) = (3x + 2)(3x + 2) = (3x + 2)2
(12x - 6)(12x + 6)
No. It's a binomial, (whose value happens to be zero no matter what 'x' is).
(x - 3)(x - 9)
3x3+12x = 3x(x2+4)
-2x+12x+28=10x+28 ;Combining like factors2(5x+14) ; Factor out a two from both of them
30+12x = 6(5+2x)
x2 + 12x + 32 = (x + 8)(x + 4)
x2 + 12x + 32 = (x + 4)(x + 8)
(x + 4)(x + 8)
(x + 10)(x + 2)
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: -6 plus or minus (3 times the square root of 2) x = -1.75735931288 x = -10.24264
