Answer to Problem 137E
The polynomial
Explanation of Solution
Given information:
The polynomial
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 difference of square of two numbers a and b is
Calculation:
Consider the polynomial
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.
Apply it,
Recall that the difference of square of two numbers a and b is
Apply it,
Thus, the polynomial
