![]() Since y cannot be negative as negative square root is not real so y = 3.ġ0. Let the consecutive integral multiple be 5n and 5(n + 1) where n is a positive integer.Īs n is a positive natural number so n = – 4 will be discarded. The product of two successive integral multiples of 5 is 300. ![]() Since the number is natural, so we consider only positive value.Ħ. A natural number, when increased by 12, equals 160 times its reciprocal. If 1/2 is a root of the equation x 2 + kx – (5/4) = 0 then the value of k isĪs one root of the equation x 2 + kx – (5/4) = 0 is 1/2Īlso Check: CBSE Class 10 Science Important MCQs: All Chaptersĥ. Hence the given equation can be solved by adding and subtracting 3/16.Ĥ. Which constant should be added and subtracted to solve the quadratic equation 4x 2 − √3x + 5 = 0 by the method of completing the square?
