Add and subtract radical expressions

Full solution

Q. Add. Write your answer in simplest form.

\newline

-8\sqrt{3} + 4\sqrt{3}

Combine like terms: Combine the like terms $-8\sqrt{3}$ and $4\sqrt{3}$ . $\newline$ Since both terms have the same radical part, $\sqrt{3}$ , we can add the coefficients directly. $\newline$ $-8\sqrt{3} + 4\sqrt{3} = (-8 + 4)\sqrt{3}$
Simplify expression: Simplify the expression by adding the coefficients. $(-8 + 4)\sqrt{3} = -4\sqrt{3}$ This is the simplest form since the radical cannot be simplified further.
