What is a Quadratic Equation?

A quadratic equation is written in the form:

ax² + bx + c = 0
Where:

• a ≠ 0
• a, b, c are numbers

Examples:

• x² + 5x + 6 = 0
• 2x² – 3x – 2 = 0

if you are interested in detailed learning of quadratic equations here are two comprehensive articles that will help you understand quadratic equations and their roots.

Methods of Solving Quadratic Equations

There are three main methods:

• Factorization method
• Completing the square method
• Quadratic formula method

Our quadratic equation solver with steps allows you to choose any of these methods.

Solve Quadratic Equation by Factorization

This method works when the equation can be written as:

(x + p)(x + q) = 0

Example:

x² + 5x + 6 = 0

x² + 5x + 6 = (x + 2)(x + 3)

So:
x + 2 = 0 → x = -2
x + 3 = 0 → x = -3

👉 Roots: x = -2, x = -3

---

Factorization Method Calculator (With Steps)

Our tool:

• Breaks the middle term
• Shows factor pairs
• Solves each factor

This makes it a quadratic factorization solver with steps, which is very helpful for beginners.

---

Solve by Completing the Square

This method converts the equation into a perfect square.

Example:

x² + 6x + 5 = 0

x² + 6x = -5

Add (6/2)² = 9 to both sides:

x² + 6x + 9 = 4

(x + 3)² = 4

x + 3 = ±2

x = -3 ± 2

👉 Roots: x = -1, x = -5

---

Completing the Square Calculator

This method is useful when:

• Factorization is difficult
• You want to understand vertex form

Our completing the square step by step solver shows every step clearly.

---

Solve Using Quadratic Formula

The most powerful method:

x = (-b ± √(b² - 4ac)) / 2a

Example:

2x² + 5x – 3 = 0

a = 2, b = 5, c = -3

D = b² – 4ac = 25 + 24 = 49

x = (-5 ± √49) / 4

x = (-5 ± 7)/4

👉 Roots: x = 1/2, x = -3

---

Quadratic Formula Solver With Steps

Our solver:

• Substitutes values
• Calculates discriminant
• Shows square root simplification
• Gives final answers

Perfect for students needing a step-by-step quadratic calculator.

---

Understanding the Discriminant (D)

D = b² – 4ac

It tells the nature of roots:

• D > 0 → Two real roots
• D = 0 → One repeated root
• D < 0 → Complex roots

👉 This is why our tool is also a discriminant calculator.

---

Find Roots of Quadratic Equation

The roots (solutions) are values of x that satisfy the equation.

Our tool acts as a:

• quadratic roots calculator
• real and complex roots calculator

---

Vertex of Quadratic Equation

The vertex is the turning point of the parabola.

Formula:

h = -b / 2a
k = value of y at h

👉 This makes our tool a vertex calculator and vertex form calculator.

---

Axis of Symmetry

The axis of symmetry is:

x = -b / 2a

It divides the graph into two equal parts.

👉 You can also call this an axis of symmetry calculator.

---

Y-Intercept of Quadratic Equation

The y-intercept is the value of y when x = 0.

So:
y = c

👉 Our tool also works as a y-intercept calculator.

---

Graph of Quadratic Equation

A quadratic equation always forms a parabola.

Our quadratic graph calculator:

• Plots the curve
• Shows vertex
• Marks roots
• Displays axis of symmetry

👉 This makes it a complete parabola graph plotter.
