I know how to get to 2y(x^3+6x-5x^2-45)

faiqraees · Answer

Very good. Now can you factorize the cubic equation?

wildemo · Answer

I am not sure how to. Aka i don't know where to go from here .

faiqraees · Answer

2y(x³-5x²+6x-45)
Can you factorize the expression in the brackets

wildemo · Answer

I am going to try:
2y[x^2(x-5)1(6x-45)] I am most likely wrong though

wildemo · Answer

Do you know what I did wrong? @FaiqRaees

faiqraees · Answer

That's not a correct way to factorize a cubic equation. Just google "factorizing cubic equations" and you can learn from there
