The product of (x+p)(x+q) can be written as x^2+(p+q)x+pq.
An intermediate step in this multiplication is
x^2+px+qx+pq=x^2+(p+q)x+pq.
Explain why px+qx=(p+q)x.
I'm Really confused please help!

by taking out the common factors.

Step-by-step explanation:

It is given that the product of is .

Given expression is

Using distributive property, we get

In middle terms px and qx the highest common factor is x. So taking out common factor from middle terms we get

It can be written as

Therefore, by taking out the common factors.
