adding and subtracting radical expressions with variables

Addition and subtraction equations worksheets - Problems. We add and subtract like radicals in the same way we add and subtract like terms. So often, as in these problems we need to simplify the radicand first. • Sometimes it is necessary to simplify radicals first to find out if they can be added or subtracted. We know that \(3x+8x\) is \(11x\).Similarly we add \(3 \sqrt{x}+8 \sqrt{x}\) and the result is \(11 \sqrt{x}\). Now square root of 45 can be written as square root of 9 x square root of 5.
