Expand the product $\left(c - 8\right) \left(5 c + 6\right)$.
Answer:
Factor $- 8 t^{2} - 80 t$.
Simplify $10 x(- 12 x + 8) +0(5 x + 7)$.
Factor $- 60 v w + 90 w^{2}$.
Simplify $4 t(7 t + 11) +0(- 10 t - 7)$.
Factor $- 63 y^{2} z + 7 y z^{2}$.
Factor $3 w^{2} + 6 w$.
Expand the product $\left(- 5 t - 3\right) \left(- 4 t - 5\right)$.
