For the best results when using the Equation Solver, follow these expert tips:
b^2 - 4ac determines root nature: >0 two real, =0 one real, <0 two complex.
For ax+b=0, x = -b/a. If a=0, there is no or infinite solutions.
x = [-b ± sqrt(b^2 - 4ac)] / 2a. It solves any quadratic equation ax^2 + bx + c = 0.
A negative discriminant means the quadratic equation has two complex (imaginary) roots involving the imaginary unit i.
Isolate the variable by moving terms. For ax + b = 0, subtract b from both sides, then divide by a to get x = -b/a.
Real roots are actual numbers on the number line. Complex roots involve the square root of a negative number and include the imaginary unit i.
Yes, for linear equations where a=0 and b≠0 (like 0x + 5 = 0), there is no solution because no x satisfies the equation.
A double root occurs when the discriminant is zero. Both roots are the same real number, and the parabola just touches the x-axis.
