In order to work with radicals (adding or subtracting) they have to have the same radical expression.
ex: 2 rad 3 + 4 rad 3 = 6 rad 3.
If it helps, change the similar radicals to a variable.
2 rad 3 + 4 rad 3
2 x + 4 x = 6x
and then substitute your radical back in for the variable.
6 rad 3
---- rad 12 - 3 rad 3
Let's simplify radical 12. First, factor 12 into a perfect square, and a not perfect square.)
Hint: we want it to be radical 3 to work with it... 3 times what is 12?
rad 12 = sqrt(12) = sqrt(4*3)
sqrt(4*3) = sqrt(4)*sqrt(3)
sqrt(4) is just 2! We bring this to the "outside" of the radical.
sqrt(4)*sqrt(3) = 2 sqrt(3) or 2 rad 3
rad 12 - 3 rad 3
2 rad 3 - 3 rad 3
(or 2x - 3x if it helps)
We're left with: -1 rad 3, or just - rad 3 (negative radical 3)

What is the simplified expression for 2 radical 20 minus 3 radical 7 minus 2 radical 5 plus 4 radical 63?
2√20 - 3√7 - 2√5 + 4√63 = 2√(4 x 5) - 3√7 - 2√5 + 4√(9 x 7) = 4√5 - 2√5 - 3√7 + 12√7 = 2√5 + 9√7
What is 12 minus r?
The expression "12 minus r" represents the subtraction of the variable "r" from the constant 12. This operation can be simplified as 12 - r. The result is a difference, where the value of "r" is subtracted from 12.
What is radical 12 times radical x?
The expression ( \sqrt{12} \times \sqrt{x} ) can be simplified using the property of square roots that states ( \sqrt{a} \times \sqrt{b} = \sqrt{a \times b} ). Therefore, ( \sqrt{12} \times \sqrt{x} = \sqrt{12x} ). Additionally, ( \sqrt{12} ) can be simplified further to ( 2\sqrt{3} ), so the expression can also be written as ( 2\sqrt{3x} ).
What is the answer to 36 degrees minus 12 feet plus 15 degree minus 32 feet?
51 degrees minus 44 feet. That expression cannot be simplified further because degrees and feet are not like terms.
