The polynomial is a difference squares. use the formula a^2 -b^2=(a+b)(a-b) to factor completely. 81x^2-49 the value of a is the value of b is the product of the prime factors is

Step-by-step explanation:

1. By definition you have that the difference of squares is:

2. Given the polynomial:

You can identify that there are two terms whose signs are different and they are perfect squares.

3. Therefore, you have:

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4
