To expand the expression (a^2 + 6a - 16) using the FOIL method, we need to multiply the terms in each pair:
F - First terms: a^2 * a = a^3
O - Outer terms: a^2 * 6a = 6a^3
I - Inner terms: 6a * a = 6a^2
L - Last terms: 6a * -16 = -96a
Now, we combine the terms:
a^3 + 6a^2 - 96a
Therefore, (a^2 + 6a - 16) = a^3 + 6a^2 - 96a.
a^2+6a-16
