Sorry wasnt allowed to use punctuation. I mean 3X*2 - 15
3x2+x-2 = (3x-2)(x+1) when factored
3x2 - 5x2 = -2x2
You can take an x squared out of both of those, leaving x squared times x plus or minus three depending on what your operation is.
3x2 - 8x = x(3x - 8)
x2 - (2x)2 = x2 - 4x2 = -3x2 x2 - 2x2 = -x2
3x2-x-2 = (3x+2)(x-1)
3x2 - 11x - 4 = 0(3x + 1)(x - 4)x = -1/3 and 4
3x2 -14x -24 can be factored as (3x + 4)(x - 6).
3x2 - 11x - 4 = (x-4)(3 x + 1)
What is the question? Do you want to factor 3x2 -x -2? If that is the question the answer is (3x + 2)(x-1)
X = 5 or -5 3x2 - 42 = 33 3x2 = 75 x2=25
3x2 + 2x - 8 = 0 is a quadratic equation.
