Answer to Problem 7OE
Factor of polynomial
Explanation of Solution
Given information: polynomial
Formula used: If the quadratic trinomial
Setting corresponding coefficients equal gives
Calculation:
polynomial
Since the coefficient of
So,
Therefore, let both pand r equal to
So, that the factorization begins
Since the constant term is
So,
Therefore, q and s must have opposite signs. There are four possibilities
Since the coefficient of y is
So,
So,
Therefore, Choose the pair of factors having sum
