1. What is the numerical coefficient of the
Answer in simplest fractional form.
2. Prove the polynomial identity
1) use binomial theorem, the first term must be to the 2, 2nd term to the 4th, to get those exponents, then you just do 6c4*(1/9)*16 which is 240/9 which is 80/3.
2) easy. just factor. and expand.
3) first choice. make values that make 2x+7=23.
