Roots are imaginary
WebExplanation: . This is true. The discriminant b 2 - 4ac is the part of the quadratic formula that lives inside of a square root function. As you plug in the constants a, b, and c into b 2 - 4ac and evaluate, three cases can happen:. b 2 - 4ac > 0. b 2 - 4ac = 0. b 2 - 4ac < 0. In the first case, having a positive number under a square root function will yield a result that is a … Webprinting To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to caclulate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is …

WebOct 19, 2024 · The axis of symmetry is the real part of the complex roots; the imaginary part can be found by subtracting the square of the axis (here, $4$) from the intercept ($13-4=9$) and then taking the square root ($3$). This assumes the roots come in conjugate pairs (so the coefficients of your quadratic are real numbers). $\endgroup$ – WebA quadratic equation has 2 roots. It will be real or imaginary. In this article we discuss the nature of roots depending upon coefficients and discriminant. If α and β are the values of x which satisfy the quadratic equation, α and β are called the roots of the quadratic equation. Roots are given by the equation (-b±√ (b 2 -4ac))/2a.

WebIn 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 equal to zero, the function calculates the ... WebMay 16, 2024 · P = (2 − i)(2 +i) = 4 +1 = 5 So the equation with these roots is: x2 −4x + 5 = 0 If we strictly answer the question and require imaginary roots then we have no real component so: Ex 3: α,β = ± 3i S = ( − 3i) +(3i) = 0 P = ( −3i)(3i) = 9 So the equation with these roots is: x2 −0x + 9 = 0 ∴ x2 + 9 = 0 Answer link
WebIn this case, we say that the roots are imaginary. Case IV: b 2 – 4ac > 0 and perfect square; When a, b, and c are real numbers, a ≠ 0 and the discriminant is positive and perfect square, then the roots α and β of the quadratic …
