4x3+10x2-6x 2x(2x2+5x-3) 2x(2x-1)(x+3)
Whatever isn't 5(x - 1)(2x + 3)
This polynomial doesn't factor. The only thing you can do is take out parts of some terms, e.g. 2(2x3 + 10x2 + x) - 3.
10x2 - 20xz + 15xy = 5x (2x - 4z + 3y)
(5x - 4)(2x + 7)
(5x - 4)(2x + 3)
10x2 + 21x - 10 = 10x2 + 25x - 4x - 10 = 5x(2x + 5) - 2(2x + 5) = (2x + 5)(5x -2)
(2x + 7)(5x - 4)
2x(2x2 - 9x + 5)
That's not as problem, unless you're practicing the procedure to simplify fractions.(10x2 - 2x)/(4x) = (10x2)/(4x) - (2x)/(4x) = 2.5x - 0.5
10x2
5x -2x = 3
