In Exercises 9 to 16, factor each trinomial product.
To factor:
The trinomial
Approach:
Factorizing a polynomial is to express the polynomial as a product of simpler expressions such that each of the simpler expressions divides the polynomial completely and also the product of all the simpler expressions gives the polynomial.
Calculation:
Given,
First look for a common factor (GCF) of the terms
But, the GCF is 1.
Now, let us factorize the given expression
First factorize the product of the coefficient of the first tern and the constant, such that the sum of the factors gives the coefficient of the middle term.
Thus, factorize
Now, split the middle term
