Weba, b < 0. If a and b are negative, then the square root of them must be imaginary: ⁺√a = xi. ⁺√b = yi. x and y must be positive (and of course real), because we are dealing with the principal square roots. ⁺√a • ⁺√b = xi (yi) = -xy. -xy must be a negative real number because x and y are both positive real numbers. WebAug 26, 2024 · To add and subtract square roots, you need to combine square roots with the same radical term. This means that you add or subtract 2√3 and 4√3, but not 2√3 and …
