Question

If B=-3q-8 and C=2q²-q-2 , find an expression that equals 3B-3C in standard form.

Answer 1

To find an expression that equals 3B-3C in standard form, substitute the given values of B and C into the expression and simplify.

Step-by-step explanation:

To find an expression that equals 3B-3C in standard form, we substitute the given values of B and C in the expression.

First, substitute B=-3q-8 into the expression: 3(-3q-8)

Next, substitute C=2q²-q-2 into the expression: -3(2q²-q-2)

Simplify the expression: -18q-24+6q²-3q+6 = 6q²-21q-18
