What is -4√12+√75 in the simplest radical form?
nekit [7.7K]

Answer: -3\sqrt{3}

Step-by-step explanation:

-4\sqrt{12} + \sqrt{75}

\sqrt{12} can be written as \sqrt{4} x \sqrt{3}

which is the same as 2\sqrt{3}

Also , \sqrt{75} can be written as \sqrt{25} x\sqrt{3} , which is the same as 5\sqrt{3}

Substituting into the main question , we have

-4 (2\sqrt{3} ) + 5\sqrt{3}

= -8\sqrt{3} + 5\sqrt{3}

= -3\sqrt{3}
