Can roots be imaginary
WebNov 15, 2024 · If \(a, b, c ∈ R,\) then the roots of the quadratic equation can be real or imaginary based on the following criteria: The roots are real when \(b^2 – 4ac≥0\) and the roots are imaginary when \(b^2 – 4ac<0.\) We can classify the real roots in two parts, such as rational roots and irrational roots. Let us know about them in brief. WebApproach to solving the question & Detailed explanation: In this program, the quadratic_roots function takes three arguments a, b, and c, which are the coefficients of the quadratic equation ax 2 + bx + c = 0. The function first calculates the discriminant b 2 - 4ac and checks if it is greater than or equal to zero. If the discriminant is greater than or …

Webf ( x) = 1 x 2 + 1 To find the vertical asymptotes, the book I'm following says that after factoring completely, you should set each factor of the denominator to 0 and: Every solution you get that does not make the numerator 0 will give you a vertical asymptote of the function. According to that, I do: x 2 + 1 = 0 x 2 = − 1 x = ± − 1 x = ± i WebMay 2, 2024 · If the value in the radicand is negative, the root is said to be an imaginary number. The imaginary number i is defined as the square root of negative 1. √− 1 = i So, using properties of radicals, i2 = (√− 1)2 = − 1 We can write the square root of any negative number as a multiple of i. Consider the square root of –25.
