**Equation calculator helps students to find the zero’s of a quadratic equations in few seconds. Using this quadratic calculator or quadratic equation solver, we can find the following characteristics of a quadratic equation.**

**1) Zero’s of a quadratic equation or roots of a quadratic equation or x-intercepts of a quadratic equation**

**2) Area bounded by the curve and the x-axis**

**3) Slope of a curve at any point on the curve**

**4) Maximum or minimum value of a curve**

**How to use this quadratic equation calculator:**

**Any quadratic equation represents a parabola. General form of a quadratic equation is Ax**

^{2}+ B x + C = 0, where A, B and C are coefficients of x^{2}term, x term and constant term respectively.**Plugging the value of A, B and C in a quadratic equation calculator, we can find solutions of a quadratic equation and other characteristics mentioned above.**

**Example:**

**Solve -x**

^{2}= -2x – 3**Step 1:**

**Write the quadratic equation in a standard form.**

**-x**

^{2}= -2x – 3**-x**

^{2}+ 2x + 3 = 0**Step 2:**

**Identify the value of A, B and C.**

**Here A = -1, B = 2, C = 3**

**Step 3:**

**Plug in the values of A, B and C in a quadratic calculator.**

**Hit the calculate button.**

**Step 4:**

**Once you hit the calculate button, you have following information about quadratic equation.**

**a) x-intercepts (or) zeros of a quadratic equation (or) roots of a quadratic equation = -1, 3**

**b) Area bounded by the parabola and x-axis = 10.67 sq units**

**c) Slope or gradient of a parabola at any point on the curve = -2x + 2**

**d) Maximum value occurs at (1, 4). Maximum value is 4.**

*Note: When it says maximum, then the parabola is open downward or concave down. If it says minimum, then the parabola is open up or concave up.***Now it’s your turn to work with this quadratic equation solver and enjoy the instant result.**
