Many students have the problem to solve a quadratic equation. Here is the step by step solution of a quadratic equation. First of all you must know what a quadratic equation is. A quadratic equation is an equation where the highest exponent of a variable is 2. Quadratic means Square that is single variable second order polynomial equation.
For example: A quadratic Equation is like
ax2 +bx +c =0 ……1
This is quadratic equation in this equation a,b,c are constant and x is variable. We will calculate the value of x over here.
To calculate value of x in this Quadratic Equation we will use formula:
± means there is two answer
Lets us take one example: 5x2 +6x +1=0
Solution: Step 1: we will compare this with equation 1 and write down the values of a, b, c constants
Step 2: Put these value in the equation 2. Then find the value of a,b,c
Stpe 3: ± read as Plus or minus as shown below: Then find the value of x
So value of x is either (-1) or (-5) .
These are the steps to solve a quadratic equation.
