Answer :
Every term has -2x in it, so factor -2x out first.
[tex] -2x^3 - 10x^2 - 12x = [/tex]
[tex] = -2x(x^2 + 5x + 6) [/tex]
Now you need two numbers that multiply to 6 and add to 5.
They are 3 and 2.
[tex] = -2x(x + 3)(x + 2) [/tex]
[tex] -2x^3 - 10x^2 - 12x = [/tex]
[tex] = -2x(x^2 + 5x + 6) [/tex]
Now you need two numbers that multiply to 6 and add to 5.
They are 3 and 2.
[tex] = -2x(x + 3)(x + 2) [/tex]
