Question

9.2 Multiplying and Factoring Polynomials 9k ( 7k+ 4 )

Answer 1

If you only want to simplify the problem, you would use the distributive property. 9k * 7k = 63$k^{2}$. Then, 9k * 4 = 36k. However, if you wanted to solve for k, you would want to set the equation equal to 0. This gives you 63$k^{2}$ + 36k = 0. After factoring, k = 0 or -4/7.
