Answer :

Final answer:

The expression 7x^5-21x^4+14x^3 factors completely to 7x^3(x^2 - 3x + 2) by first identifying and pulling out the greatest common factor, 7x^3.

Explanation:

We are trying to factor completely the polynomial 7x^5-21x^4+14x^3. Factoring completely means expressing an algebraic expression as a product of its simplest factors.

The first step in factoring any expression is to identify the greatest common factor. In our problem, the greatest common factor is 7x^3. We can write out all of the terms divided by 7x^3:

7x^5 ÷ 7x^3 = x^2

-21x^4 ÷ 7x^3 = -3x

14x^3 ÷ 7x^3 = 2

We use the above results as the terms for a new polynomial and multiply it by our factor. Here's our completely factored equation:

7x^3(x^2 - 3x + 2)
