-x(x2 - 2)(x2 + 3)
x2-3x+2.25 is the same as 4x2-12x+9 and is (2x-3)(2x-3) when factored
9x(x2+3x-10) * * * * * 9x3 + 27x2 - 90x = 9x(x2 + 3x - 10) = 9x(x + 5)(x - 2).
(3x + 5)(x2 - 2)
First take out -3x to make-3x(x2+11)If you're not using imaginary numbers, then you're done. Otherwise factor x2+11 using the sum of two squares rule.-3x(x-sqrt(11)i)(x+sqrt(11)i)
x2-3x-28
x2 + 3x - 40 = (x + 8)(x - 5)
3(x2 + 3x + 1)
3 - 3x + x2 - x3 = (1 - x)(x2 + 3)
x3 + x2 - 3x - 3 x(x2 + x - 3) - 3
(x2 + 3x + 5)(x2 - 3x + 4)
x2 + 3x + 28 can not be factored. If on the other hand you meant to type: x2 + 3x - 28 That can indeed be factored: = x2 + 7x - 4x - 28 = x(x + 7) - 4(x + 7) = (x - 4)(x + 7)
(x-4) (x+7)
(x + 3)(x + 4y)
=3x * * * * * The correct answer is: x2 + 7x + 12 = (x + 3)(x + 4).
(x-1)(x+4)
(x - 1)(x - 2)
