Simplify (2p+3)2 - (2p-3)2 (give proper detailed answer with all steps)

Step-by-step explanation:

There's a very useful pattern in factoring and multiplying binomials called a difference of squares, and it looks like this:

We can use this difference of squares to factor the expression we've been given, setting and to obtain the expression

(1)

tackling each of the multiplicands on the right:

(Left)

(Right)

This simplifies the expression on the right of (1) to , or simply .

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
