Quadratic equation calculator
Quadratic equation has the basic form: ax2+bx+c=0Enter the quadratic equation's coefficients a, b, and c of its basic standardized form. A solution of quadratic equations is usually two different real or complex roots or one double root — the calculation using the discriminant.
Calculation:
−7x2+4=0 −7x2+4=0 7x2−4=0 x1,2=±4/7=±0.755928946 x1=0.755928946 x2=−0.755928946
Solution in text:
-7x2+4=0 ... b=0; pure quadratic equationDiscriminant:
D = b2 - 4ac = 112
D > 0 ... The equation has two distinct real roots
x1 = 0.7559289
x2 = -0.7559289
P = {0.7559289; -0.7559289}
