Question

factor the trinomial completely
10x^3-26x^2-12x

Answer 1

\[10x^3-26x^2-12x\]pull out the greatest common factor:\[2x(5x^2-13x-6)\]\(-13\) can be split into \(-15\) and \(2\):\[2x(5x^2-15x+2x-6)\]group the terms:\[2x[(5x^2-15x)+(2x-6)]\]factor out the commons from each set of parenthesis:\[2x[5x(x-3)+2(x-3)]\]rearrange:\[2x[(5x+2)(x-3)]~~\checkmark\]

Answer 2

how do you get - 15 from -13

Answer 3

i see -15 + 2=-13

Answer 4

so the answer is 2x[(5x+2)(x-3)]

Answer 5

yup :)
