the equation is 2*2 to the second power plus 3 *2 *-4 minus 4* -4 to the second power. i keep getting 48 but the answer choices are -80 -32 32 and 80
Could you write this out ???....it's difficult to tell what you have from the description
2*2^2+3*2*-4^2= there you go Cphil
2*2^2+3*2*-4^2 =
2 * 4 + 6* (-1) * 4^2 =
8 - 6 (16) =
8 - 96 =
-88
