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 Ax2 + B x + C = 0, where A, B and C are coefficients of x2 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 -x2 = -2x – 3
Step 1:
Write the quadratic equation in a standard form.
-x2 = -2x – 3
-x2 + 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.
