Which of the following is one of the two binomial factors of 6s2 + 40s – 64?
a. s + 10
b. 2s – 16
c. 6s – 12
d. 3s – 4

Binomial Factors really just mean factors of a polynomial, in this case there are two so hence the binomial name. If you are unsure of how to solve a quadratic equation, the best thing is to first simple the coefficients and then move to the quadratic formula. Since all the factors are divisible by 2, you can divide 2 out of the entire expression, so now it will look like . Now that the coefficients are completely simplified, you can put the coefficients into the quadratic formula, , where a is the coefficient with the , b with and c the -32. When you plug in the values for a, b and c into the two equations, the two solutions you come up with are . If you put this back in factor form, it would look like . Matching that with the choices you were given, D. is the answer
