Equation Solver کے بارے میں
The Equation Solver solves two types of algebraic equations: linear equations of the form ax + b = c, and quadratic equations of the form ax^2 + bx + c = 0. Enter the coefficients and receive the solution(s) with a clear step-by-step explanation of the method used.
For quadratic equations, the solver uses the quadratic formula and handles all three discriminant cases: two distinct real roots (positive discriminant), one repeated real root (zero discriminant), and two complex conjugate roots (negative discriminant). Steps are shown for each case.
All computation runs in your browser with no server calls. This makes the tool ideal for checking homework solutions, understanding algebra steps, and quickly solving equations during study sessions or problem-solving.

مسئلہ حل کرنا
Setting a = 0 in quadratic mode
حل
If a = 0, the equation is linear (bx + c = 0), not quadratic. Switch to linear mode or ensure a is non-zero for quadratic solving.
Expecting real roots when the discriminant is negative
حل
A negative discriminant means the quadratic has no real roots — only complex conjugate roots. The calculator will show the complex form (e.g., 2 + 3i and 2 - 3i).
Entering the equation in the wrong format
حل
The solver requires you to enter coefficients separately (a, b, c), not the full equation as a string. Rearrange your equation to standard form first.
اکثر پوچھے جانے والے سوالات
What types of equations can the solver handle?
Linear equations (ax + b = c) and quadratic equations (ax^2 + bx + c = 0). For cubic or higher-degree equations, the solver is not applicable.
What is the quadratic formula?
x = (-b +/- sqrt(b^2 - 4ac)) / (2a). The discriminant b^2 - 4ac determines whether there are two real roots (positive), one root (zero), or two complex roots (negative).
What does a negative discriminant mean?
A negative discriminant means the square root is imaginary, so the quadratic has no real solutions. The roots are complex numbers of the form a + bi and a - bi.
Can I solve equations with decimal coefficients?
Yes. Enter decimal values for a, b, and c (e.g., 0.5, 2.3, -1.7). The calculator handles all real number coefficients.
How do I convert my equation to the standard form?
For linear: rearrange to ax + b = c. For quadratic: rearrange to ax^2 + bx + c = 0 by moving all terms to one side.
What if a = 0 in the quadratic form?
If a = 0, the equation reduces to a linear equation bx + c = 0. The solver handles this as a special case, but it is cleaner to use linear mode directly.
Does the solver show intermediate steps?
Yes. Each step of the solution process is displayed, from identifying the discriminant value to substituting into the quadratic formula and simplifying.
Is my data private?
Yes. All calculations run entirely in your browser. No equation data is transmitted to any server.
