2-140.

Substitute 0 for *x* and simplify.

*h*(0) = −3(0)^{2} − 11(0) + 4

*h*(0) = 4

See part (a).

*h*(2) = −30

Be careful of the signs when multiplying negative numbers.

*h*(−1) = 12

Remember how to multiply fractions.

0 = −3*x*^{2} − 11*x* + 4

Start with the diamond problem and factor using a generic rectangle.
