WebSep 5, 2024 · There are two keys to combining radicals by addition or subtraction: look at the index, and look at the radicand. If these are the same, then addition and subtraction are possible. If not, then you cannot combine the two radicals. Making sense of a string of radicals may be difficult. WebLook at that—the answer a = 9 does not produce a true statement when substituted back into the original equation. What happened? Check the original problem:.Notice that the radical is set equal to −2, and recall that the principal square root of a number can only be positive.This means that no value for a will result in a radical expression whose positive …
