1. Solve algebraically for... 1.) 4x*(x^2-5)+(x^2-5)^2=0 two separate problems not relating to each other 2.) 4x^3*(1-x)^3-3*(1-x)^2*x^4=0 2. this symbol ^ is to the power of. all x's are the x variable as written in my precalc book. For problem 1. I see that (x^2-5) is similar to (x^2-5)^2 but the ^2 outside of the brackets is throwing me off. Same goes for problem 2., i see that (1-x) is a common factor but the exponents are throwing me off. The variable x should have an answer using the zero product rule. 3.
