Multiply polynomial $- 18 x - 4 x - 1$ by $5 x + 10$ .

Answer

$(- 18 x - 4 x - 1) \cdot (5 x + 10) = - 110 x^{2} - 225 x - 10$

Explanation

Step 1: First we have to write polynomials in descending order.

P (x) Q (x) = - 22 x - 1 = 5 x + 10

In this example we are multiplying two binomials so FOIL method can be used.

(- 22 x - 1) \cdot (5 x + 10) = FIRST (- 22 x) \cdot 5 x + OUTER (- 22 x) \cdot 10 + INNER (- 1) \cdot 5 x + LAST (- 1) \cdot 10 = = - 110 x^{2} + (- 220 x) + (- 5 x) + (- 10) = = - 110 x^{2} + (- 220 x) + (- 5 x) + (- 10) = = - 110 x^{2} - 225 x - 10;
