2-28.

Factor each expression below completely. Homework Help ✎

*x*^{2}− 2*x*− 632

*x*^{2}− 5*x*−12

Try to think of two factors of 63 that have a difference of 2.

Notice that the constant, −63, is negative.

(*x* − 9)(*x* + 7)

Try using a diamond problem and a generic rectangle.

To get 2*x*^{2} you need factors (2*x* )(*x* ).

(2*x* + 3)(*x* − 4)
