WebThe quadratic formula says that x=\dfrac {-\goldD {b}\pm\sqrt {\goldD {b}^2-4\purpleD {a}\redD {c}}} {2\purpleD {a}} x = 2a−b ± b2 − 4ac for any quadratic equation like: \purpleD {a}x^2 + \goldD {b}x + \redD {c} = 0 ax2 + bx + c = 0 What is the discriminant? WebStart Declare variables a,b,c. Initialize the variables a,b,c. Calculate the roots of the quadratic equation in the main method itself. Check whether roots are possible or not using condition a==0. Calculate the discriminant as Discriminant= sqrt ( (b*b)- (4*a*c)). If discriminant.>0, then the roots are real and unequal.
WebOct 6, 2024 · Calculate the Discriminant. The quantity Δ = b² – 4ac is called the discriminant of the quadratic equation. To calculate b squared in java, we have two solutions: multiply b by itself. use Math.pow to raise it to the power of 2.
