Factor out the common factor to combine the radicals expressions.
4sqrt(3x)
Practice makes perfect
Radicals can only be added or subtracted when they have like radicands.
a sqrt(x) + b sqrt(x) = (a+b) sqrt(x)
asqrt(x)-bsqrt(x)=(a-b)sqrt(x)
Since all of the radicands are alike, so we can perform the addition and subtraction by factoring out the common factor.
