I am trying to compute the solutions to

I factored all the way up to

Which gave me 3 out of 4 solutions

My book says the final solution is but I don't see how they got that.

Factorise the last term x^2+5x =x(x+5) then you will find x = 0 the fourth root...................

the complete factorization is x(x-3)(x+3)(x+5) ........... - Jun 20th 2013, 09:11 PMReneGRe: Solutions to 4 Degree Polynomial
I'm such a dunce, thanks.
