Cubic Equation Solver کیا ہے؟
A cubic equation has the form ax³ + bx² + cx + d = 0 and always has three roots (which may be real or complex, and some may be repeated). Cardano's formula (1545) was the first general algebraic solution for cubics, though numerical methods are used in practice.
فارمولا
- x
- t − b/(3a) to eliminate the x² term — t − b/(3a) to eliminate the x² term
مرحلہ وار گائیڈ
- 1Depress the cubic: substitute x = t − b/(3a) to eliminate the x² term
- 2Solve the depressed form t³ + pt + q = 0 using Cardano's formula
- 3Three real roots occur when the discriminant Δ = −4p³ − 27q² > 0
- 4One real root when Δ < 0, three roots (one repeated) when Δ = 0
