.
The square root of 8 can be simplified as the product of an integer and the square root of 2:
.
As a result,
.
Step Two: Expand the product of the two binomials.
is the product of two binomials:
- Binomial One:
.
- Binomial Two:
Start by applying the distributive law to the first binomial. Multiply each term in the first binomial (without brackets) with the second binomial (with brackets)
Now, apply the distributive law once again to terms in the second binomial.
.
Step Three: Simplify the expression.
The square of a square root is the same as the number under the square root. For example, .
.
Combine the terms with the square root of two and those without the square root of two:
.
Factor the square root of two out of the second term:
.
Combining the steps:
.
