Question

Factor -x^3+3x-2

Answer 1

-(x-1)(x+2)(x-1) now simplify this.

Answer 2

-(x-1)^2(x+2)

Answer 3

How do you get that so easily?

Answer 4

So you find what values you have to multiply to get 2

Answer 5

so like 1 times 2 is 2.

Answer 6

there really isn't any other solution because that would be the only values that make 2.

Answer 7

Also these two values, 1 and 2 have to add up to the middle number.

Answer 8

Which is 3

Answer 9

ok... I'm still not sure how you find the three factors so easily. It looks like you're doing a trick similar when you have like x^2+bx+c.. finding two numbers that multiply to give c and adding them gives b... but I'm not sur ehow it's done with the ^3 at the front
