Advanced Math practice question

Answer: A. 2x + 5

(3x − 4)(2x + 5) = 6x² + 15x − 8x − 20 = 6x² + 7x − 20.

Why the other answers are wrong

B. 2x − 5

(3x − 4)(2x − 5) gives −23x as the middle term, not +7x.

C. 3x + 5

(3x − 4)(3x + 5) starts with 9x², not 6x².

D. 2x + 4

(3x − 4)(2x + 4) ends in −16, not −20.
