To calculate: The real solutions of the equation
Answer to Problem 78RE
The solutions of the equation are
Explanation of Solution
Given information:
The equation is given as
Formula used:
In order to find all the solutions to higher-degree equation, use synthetic division, factoring, and the Quadratic Formula.
In order to Factorise the high degree polynomial, determine all the terms that were multiplied together to get the given polynomial. Then try to factor each of the terms found in the first step. This continues until it can’t be factored anymore. When it can’t be factored, then polynomial is completely factored.
For an equation of the form
Calculation:
Consider the equation
Convert this equation into
Then, the equation
Therefore, the solution of this equation is given by
Now , since
Thus, the real solutions of
