x2-3x+2.25 is the same as 4x2-12x+9 and is (2x-3)(2x-3) when factored
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions:-6 plus or minus 2 times the square root of 2 x = -3.1715728752538097 x = -8.82842712474619
x2 + 18x - 50 does not have rational factors.
Assuming the question is written as: x2+11x-12 This would factor to: (x+12)(x-1)
(x + 5y)(x - 3y)
x2 + 12x + 32 = (x + 8)(x + 4)
x2 + 12x + 32 = (x + 4)(x + 8)
(x + 8)(x + 4)
3x3+12x = 3x(x2+4)
x2-12x+35 = (x-5)(x-7)
(x + 10)(x + 2)
x2 - 12x + 32 = 0 x2 - 8x - 4x +32 = 0 x(x -8) - 4(x -8) = 0 (x - 4)(x - 8) = 0 x = 4 or x = 8
x(x + 4)(x - 3)
x2+12x+28Improved Answer:--x2+12x+28 = (-x+14)(x+2) when factored
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
x2 + 12x + 27 = (x + 9)(x + 3)
x2-12x+36 = (x-6)2
