Question

What is the product? negative 9 x (5 minus 2x) 18 x squared minus 45 x negative 18 x squared minus 45 x negative 18 x minus 45 x 18 x minus 45 x

Answer 1

For this case we must find the product of the following expression:

$-9x (5-2x)$

Applying distributive property to terms within parentheses and taking into account that:

$- * + = -\\- * - = +$

we have:

$(-9 * 5) (x) + (9 * 2) (x * x)\\-45x + 18x ^ 2$

Answer:

$-45x + 18x ^ 2$

Option A
