Dividing by a square root
WebIt is often customary to rationalize the denominator to ensure that there are no square roots by using three principles. First, you can always multiply a number by 1 and not change it. Second, any fraction of the form √x/√x can be used as 1. Finally, by definition, √x × √x = x. For example, consider the fraction 15/ (2√5). WebDividing surds Just like the method used to multiply, the quicker way of dividing is by dividing the component parts: \ [\frac {8 \sqrt {6}} {2 \sqrt {3}}\] Divide the whole numbers: \ [8...

WebTo add square roots, we need like radicals (which have the same radicand, or number under the radical). To multiply or divide square roots, we simplify by factoring out perfect squares (like 4, 9, 16, etc.) from the resulting radicand. In some cases, we may also need to rationalize the denominator.
WebWhen dividing a square root by another, we can simplify the coefficients and radicands, separately. After those simplifications, we rationalize the denominator by multiplying both the numerator and denominator with the … Web(x²+1) divides x⁴ + ax² + bx + 2 - (-x +1) = x⁴ + ax² + (b + 1) + 1 exactly. Since (x²+1) = (x + i) (x - i) this tells us (x - i) also divides x⁴ + ax² + (b + 1)x + 1 and, by the Polynomial Remainder Theorem, i is a zero. Substituting x = i in to x⁴ + ax² + (b + 1)x + 1 = 0 gives: 1 - a + (b + 1)i + 1 = 0
