Multiply polynomial $6 c^{5} - 2 c^{4} - 2$ by $- 11 c^{2} - 15$ .

Answer

$(6 c^{5} - 2 c^{4} - 2) \cdot (- 11 c^{2} - 15) = - 66 c^{7} + 22 c^{6} - 90 c^{5} + 30 c^{4} + 22 c^{2} + 30$

Explanation

We can multiply polynomials by using a GRID METHOD

Write one of the polynomials across the top and the other down the left side.

- 11 c^{2} - 15 6 c^{5} - 2 c^{4} - 2

Fill in each empty box by multiplying the intersecting terms.

- 11 c^{2} - 15 6 c^{5} - 66 c^{7} - 90 c^{5} - 2 c^{4} 22 c^{6} 30 c^{4} - 2 22 c^{2} 30

Combine like terms:

- 66 c^{7} + 22 c^{6} - 90 c^{5} + 22 c^{2} + 30 c^{4} + 30 = - 66 c^{7} + 22 c^{6} - 90 c^{5} + 30 c^{4} + 22 c^{2} + 30
