4) Expand the binomial using Pascal's Triangle for the coefficients. Simplify. (x+4)^4
(x+4)^4=x^4+16x^3+96x^2+256x+256
2) Expand the binomial using Pascal's Triangle for the coefficients. Simplify. (x+a)^2
(x+a)^2=x^2+2xa+a^2
3) Expand the binomial using Pascal's Triangle for the coefficients. Simplify. (x-3)^3
(x-3)^3=x^3-9x^2+27x-27
5) Expand the binomial using Pascal's Triangle for the coefficients. Simplify. (x-4)^4
(x-4)^4=x^4-16x^3+96x^2-256x+256
