Simplifying a radical binomial squared by using foil, (3sqrt(2) - 2sqrt(3))^2
👉 Learn how to multiply radicals. A radical is an expression or a number under the root symbol. To multiply the sum/difference of two or more radicals, we make use of the distributive property to expand the product and then simplify the...
