Answer:
Expand (7n+8) (5n−8)
using the FOIL Method.
(7n (5n) + 7n ⋅ − 8 + 8 (5n) + 8 ⋅ − 8 (−2n + 12)
Simplify and combine like terms
(35n² − 16n − 64) (−2n + 12)
Expand (35n² − 16n − 64) (−2n + 12)
by multiplying each term in the first expression by each term in the second expression.
35n² (−2n) + 35n² ⋅ 12 − 16n (−2n) − 16n ⋅ 12 − 64 (−2n) −64 ⋅ 12
Simplify terms.
−70n³ + 452n² − 64n − 768
i simplified it hehe, not sure, please correct me if im wrong :))
