a.
To calculate: The equation
a.
Answer to Problem 3E
The solution of the equation
Explanation of Solution
Given information:
The equation
Formula used:
Steps to use this method to solve a quadratic polynomial
Step 1. Check the equation for real numbers which satisfy the equation that means the value of
Step 2. Check the equation for
Step 3. Now get the real roots of the equation.
Calculation:
The graph of the equation
So find the real roots of the equation
Rewrite the equation
Check for the real number
The value of
Now check for real number
The real no
Now check for real number
The real no
Now check for real number
The real number
Now check for real number
The real no
Now we get the four real roots
The solution of the equation
