7x2 -4x -5x2 +2x = 2x2 -2x
2(2x-11)(3x+5)
8x3 is 2x cubed.
Oh, dude, that's just a fancy way of saying 2 times x squared minus 2 times x. So, like, you just gotta multiply x squared by 2 and x by 2, which gives you 2x squared minus 2x. It's like math, but with extra steps to make it seem more complicated than it is.
(2x - 1)(5x + 8)
2x(x−6)(x+1)
(2x3 - x2) = x2 (2x - 1)
4
2x squared minus 4
4x3+10x2-6x 2x(2x2+5x-3) 2x(2x-1)(x+3)
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
7x2 -4x -5x2 +2x = 2x2 -2x
2x squared - 5x - 3 = (2x +1)(x -3)
-x2+2x
200x
2x(2x - 1)
6x3 + 9x2 - 2x2 - 3x Before any grouping, take out the common factor, x, to give x*(6x2 + 9x - 2x - 3) = x*[3x*(2x + 3) - 1*(2x + 3)] = x*(2x + 3)*(3x - 1)
