WebIf 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 … WebThe square root of a negative number, say, -y, is: √ (-y)= i√y, where ‘i’ is the square root of -1. Square root of Complex Numbers To find the square root of complex numbers is a little complicated. We can find the square root of a+ib using the below formula: a + b i = ± ( a 2 + b 2 + a 2 + i a 2 + b 2 − a 2) where a+ib is a complex number.
Weba = ± i b − b 2, where i is the imaginary unit, which by definition is the unique complex number that satisfies i 2 = − 1 ⇔ i = ± − 1. The complex numbers are numbers of the form a + b i, … WebMay 12, 2024 · By mistakenly taking the square root, you introduced the negative term, which was never there in the first place. You might have been able to see your mistake by graphing the equation. This is a parabola that opens up with the vertex at ( 9 2, 0). (A parabola with a vertex on the x -axis always has a double root.)
