Simplify the equation.

Question

-12/√6-3

 

 

negative 12 divided by the square root of 6 minus 3

Answer 1

Multiply the numerator and denominator by:

 

√6 + 3

 

And then simplify. You want to do this because:

 

(a + b)(a - b) = a² - b²

 

and it will get the √ sign out of the denominator. Use this approach for any similar problem.
