I need some help on figuring out how to solve these equations, the directions say the problems represent a mix of linear, quadratic, and third degree polynomial equations. Here they are:
1.) y^3 +3y^2 - 4y - 12= 0
2.) 2x^3 + 3x^2 = 8x +12
3.) 2a (a+1) = a^2 +8
4.) 2x^3 + x^2 = 32x +16
Thanks for your help! It's appreciated!
