Question

Simplify the expression –3(x + 3)2 – 3 + 3x. What is the simplified expression in standard form?

Answer 1

Answer:

$-3x^2-15x-30$

Step-by-step explanation:

The given expression is $-3(x+3)^2-3+3x$.

We expand to obtain:

$-3(x^2+6x+9)-3+3x$.

We apply the distributive property to get:

$-3x^2-18x-27-3+3x$.

Group and combine the like terms;

$-3x^2-18x+3x-27-3$.

$-3x^2-15x-30$.

This polynomial expression is in standard form because it is descending powers of x.
