Question

Factor this expression.

Answer 1

Answer:

Step-by-step explanation: If we want to multiply a sum by another number, either we can multiply each term of the sum by the number before we add or we can first add the terms and then multiply. For example,

In either case the result is the same.

This property, which we first introduced in Section 1.8, is called the distributive law. In symbols,

a(b + c) = ab + ac or (b + c)a = ba + ca

By applying the distributive law to algebraic expressions containing parentheses, we can obtain equivalent expressions without parentheses.

Our first example involves the product of a monomial and binomial.

Example 1 Write 2x(x - 3) without parentheses.

Solution

We think of 2x(x - 3) as 2x[x + (-3)] and then apply the distributive law to obtain

The above method works equally as well with the product of a monomial and trinomial.

Answer 2

Step-by-step explanation:

3x²-15x

3x(x-5)

When you multiply you will get the expression given that's why it's the correct answer to the question

So the answer is C
