Chapter 4.2, Problem 11C

To determine

To find greatest common factor of given monomial.

Answer to Problem 11C

4x

Explanation of Solution

Given Information: $20x^2,36x$

Formula used: Calculate Greatest common factor using factor method of monomial.

Calculation:

The factors of 20 are: $20x^2=2\times 2\times 5\times x\times x$

The factors of $36x$ are: $36x=2\times 2\times 3\times 3\times x$

Since $2\times 2\times x$ is common between both factors, then the greatest common factor is 4x.

 The final answer: 4x
