Factor 2x2 - 11x - 21. a) (2x + 3)(x - 7) eliminate b) (x + 3)(2x - 7) c) (2x - 3)(x + 7) d) (2x + 7)(x - 3)

The first step for factoring this expression is to write -11x as a difference. 
2x² + 3x - 14x - 21
Factor out x from 2x² + 3x.
x × (2x + 3) - 14x - 21
Now factor out -7 from -7(2x + 3)
x × (2x + 3) - 7(2x + 3)
Finally,, factor out 2x + 3 from the expression.
(2x + 3) × (x - 7)
This means the correct answer to your question is (2x + 3) × (x - 7),, or option A.
