... Do you see the similarity between the original polynomial? By taking out a common exponent, I've reproduced an equation extremely similar to , just with a different variable. I've created .
Let's just pretend y^2 is equivalent to x, for the sake of simplicity. You found the original polynomial, factored, to be
By re-substituting (y^2) into the factored form of the polynomial we get:
Do you understand my thought process? Are you able to finish it off?
