Answer to Problem 13OE
The trinomial
Explanation of Solution
Given information:
The trinomial
Formula used:
To factor a polynomial split the middle term in such a way that sum of two numbers is the middle term and product of two numbers is same is product of first and last term.
The square of difference of two numbers a and bis
Calculation:
Consider the trinomial
Recall that to factor a polynomial split the middle term in such a way that sum of two numbers is the middle term and product of two numbers is same is product of first and last term.
In the above polynomial there does not exist two numbers such that their sum is
Also the square of difference of two numbers a and bis
The trinomial is rewritten as,
Thus, the trinomial
