Mathematics
1 answer:
inysia [295]3 years ago

Answer:

Step-by-step explanation:

Take the area of the yard and subtract from it the area of the pool.  In quadratic form, the area of the pool is

2x^2-x-28

Subtracting the area of the pool from the area of the yard:

3x^2-14x-5-(2x^2-x-28)

Since the negative in front of the parenthesis will change the signs inside:

3x^2-14x-5-2x^2+x+28

Combine like terms to get the area left after the pool goes in:

x^2-13x+23
