Multiplying Two Binomial Expressions with Radicals Together

The video tutorial explains the FOIL method for multiplying binomials, focusing on the steps of multiplying the first, outer, inner, and last terms. It highlights the handling of terms with square roots, emphasizing that multiplication is only possible when both terms are under the same root. The tutorial also covers the subtraction of terms with square roots, ensuring they have the same radicand. The final calculation is demonstrated, leading to the conclusion of the problem-solving process.

What does the FOIL method stand for in algebra?

• First, Outer, Inner, Least

• First, Outer, Inside, Last

• First, Only, Inner, Last

• First, Outer, Inner, Last

When multiplying a number with a square root, where should the number be placed if it is not under the root?
