Jamar is attempting to factor the expression 15x^2-16x-15. In his first step, he rewrites the expresssion as 15x^2-25x+9x-15. Which of the following statements in true about jamar's work?

A. Jamar's first step is correct. He should continue to factor the expression.
B. The two middle coeffiecient add to the correct number, but do not mulitply to the correct number.
C. The two middle coefficients multiply to the correct number, but do not add to the correct number.
D. The two middle coefficients do not add or multiply to the correct number.
