Chapter 6: Q 85E (page 589)

In the following exercises, factor each trinomial of the form
$x^{2} - 3 x y - 14 y^{2}$

Short Answer

Expert verified

The trinomial is prime. Hence there is no factors for the equation.

Step by step solution

Step 1. Given information

The given equation is $x^{2} - 3 x y - 14 y^{2}$

Step 2. Writing factors as two binomial with first term x and second term y.

The factors should be written as two binomials with first term r and second term s.

$(x y) (x y)$

The product of the two numbers is 14,and their sum is 3. Because the third term sign is negative, the sum seems to be a difference.

There are no factors pair that sum is 3. The given trinomial is prime.
