Question

Factorise into linear factors, where possible:
x^3+2x^3-11x-12

Answer 1

I think it has only one real linear factor.

Answer 2

the 2x...is it supposed to be squared or is it really cubed?

Answer 3

it really is squared

Answer 4

no wait!

Answer 5

sorry it is squared

Answer 6

you can use synthetic/long division to find linear factors...

Answer 7

x^3+2x^2-11x-12 will factor into the product of 3 linear factors.

One of the factors is ( x - 3).

To get the other two, you can divide (x-3) into (x^3+2x^3-11x-12) and factor the quotient.

x^3+2x^3-11x-12 = (x - 3) ( x + ? ) ( x + ?? )
