The binomial factors of the quadratic trinomial may take the forms of (y + a) and (y + b). The sum of a and b is equal to the numerical coefficient of the second term and their product should be equal to the constant. If a is equal to -2, b is equal to -8. Thus, the second factor is (y - 8).
Answer: +15x
Explanation: Don't be thrown off if a variable like <em>x</em> is introduced in a multiplication problem that involves positives and negatives.
To simplify (+3) (+5x), it's important to understand that a positive times a positive is a positive. So (+3) (+5x) is +15x.

3/x-4=7/x
*cross multiply
3x=7 (x-4)
3x=7x-28
28=7x-3x
28=4x
x=7
