What is the value of the expression x³ - 2x² + 4x + 4, for x = -2 ?

A.) 12

B.) -2

C.) -4

D. -8

E.) -20

A.) 12

B.) -2

C.) -4

D. -8

E.) -20

x³ - 2x² + 4x + 4

= (-2)³ - 2(-2)² + 4(-2) + 4 {substituted -2 in for x}

= -8 - 2(4) - 8 + 4 {evaluated exponents}

= -8 - 8 - 8 + 4 {multiplied}

=

**-20**{added and subtracted from left to right}
