we may be able to manipulate the radicals to get like radical parts and then add as we did earlier. As we said, we're working with square root radicals, so the radical of a number is equal to the number that when multiplied by itself gives that number. For instance, sqrt(9)=3, be...

Example 1: Find Three Fractions Equivalent to 3/4 For each equivalent fraction, we just need to pick a number to multiply the numerator and denominator by. 2 is an easy one to start with. 3×2 / 4×2 = 6/8 Recommended How to Add, Subtract, Multiply and Divide Fractions Let's use...
If the radicands of the square roots are not the same, then they are not like radicals, and we cannot combine them. So, if we have $\sqrt{2}$ and $\sqrt{3}$, we cannot add or subtract one of them from the other. The radicands are different (one is 2 and the other...

Since both terms have the same radical part (radical 6), we can subtract the coefficients in front of the radicals. This gives us -3 radical 6 as the simplified answer. What is the answer to this problem 3 minus y over y to the second power minus 2y minus 3? If you multiplie...
