# Note: Exercises preceded by an asterisk are of a more challenging nature.In Exercises 1 to 4, factor by using the GCF. 5 y 3 - 20 y 2

To determine

To factor:

To factor using the GCF.

5y3-20y2

Explanation

Approach:

Factorizing a polynomial is to express the polynomial as a product of simpler expressions such that each of the simpler expressions divides the polynomial completely and also the product of all the simpler expressions gives the polynomial.

Calculation:

Given,

5y3-20y2

First let us find the GCF as the terms in the above expression.

Thus, the GCF as the terms

5y3, -20y2 is 5Â·yÂ·y=5y2

Thus, the given expression can be expressed as

=5y3-20y
