C2 Algebra - easy question? Watch
Quick help is appreciated.
Then x^3 + x^2 - 5x- 5 = 0
Factorising to (x^2-5)(x+1)
Hope this helps.
Sure. (x-2)(x+1) is x^2 -x -2
x^3 + x^2 - 4x - 4 = x^2 -x - 2
So you just factorise x^3 - 3x - 2 into (x+1)^2(x-2)
I get the wrong answer, can I not factorise the original f(x) first?
Need a quick reply, kind regards.
