Solve the equation

Answer to Problem 9GR
Solutions of the equation
Explanation of Solution
Given:
The equation:
Concept Used:
Zero-Product Property: If we multiply two (or more) things together and the result is equal to zero, then we know that at least one of those things that we multiplied must also have been equal to zero.
Calculation:
Middle Term Factorization:
In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term.
To Factor the form : | Factor : |
1) Find the product of 1st and last terms ( | |
2) Find the factors of | |
3) Write the middle term using the sum of the two new factors, including the proper signs. | |
4) Group the terms to form pairs - the first two terms and the last two terms. Factor each pair by finding common factors. | |
5) Factor out the shared (common) binomial parenthesis. | ( |
Now use zero product property:
Thus, Solutions of the equation
