Factor and simplify each expression below. Homework Help ✎
Justify each step in simplifying the expression in part (a).
Factor and then reduce.
For the numerator, what numbers multiply to −6 and add to −5?
Put these numbers in a generic rectangle (these create your "middle term") along with the first and last terms.
Now find the greatest common factors of each row and column.
See the generic rectangle.
2x2 − 5x − 3 = (x − 3)(2x + 1)
Now factor the denominator and simplify.
