The polynomial is .
The general quadratic expression form is .
In the above trinomial, .Since
is negative, so the factors m and p have opposite signs.So either m or p is negative, but not both.
Since is positive, the factor with the greater absolute value is also positive.
You need to find one factor of each pair is negative with a sum of 9 and a product of .
Make a list of the factors of and look for the of factors with the sum of 9.
The correct factors are .
Apply the pattern: .
Group terms with common factors.
\Factors the GCF from each group.
\Notice that is common in both groups, so it becomes the GCF.
Apply distributive property: .
The factors form of equation is.
Apply zero product property: .
Solve the first equation, .
Solve the second equation, .
Add 3 to each side.
\Divide each side by 2.
\.
