Geometry 8-0 Simplify Radicals • Radical: a number with a square root symbol Radical sign Coefficient- # outside the square root Radicand- # under the square root
Adding and Subtracting • In order to add and subtract radicals, the radicand must be the same. • Just add or subtract the coefficients, leave the radicand alone. Ex)
Simplifying Radicals • Some radicals can be simplified so that the radicand is a smaller number. • To do that, use a factor tree. Ex)
