PLEASE MATH EXPERT!
I am struggling thank you

Step-by-step explanation:

This is just a big multiplication, but it gets more simple when you break it into steps.

First consider . This multiplies out to

Next, . This is

Finally, . This is

Sum these three expressions together and you get

Step-by-step explanation:

(x² + 3y  + y²)(x² + 3y - y²)

= x²*(x² + 3y - y²)  + 3y*(x² + 3y - y²)  + y²((x² + 3y - y²)

= ( x²*x² + x²*3y - x²*y²)   +  [3y*x² + 3y*3y  - 3y*y²]   + {y²*x² + y²*3y  - y²*y²}

= x⁴ + 3x²y - x²y²   + 3x²y + 9y² - 3y³  + x²y² + 3y³ - y⁴

= x⁴  + 3x²y + 3x²y - x²y²  + x²y²  + 9y²  - 3y³ + 3y³ - y⁴

= x⁴ + 6x²y  + 0 + 9y² + 0 - y⁴

= x⁴ + 6x²y + 9y² - y⁴

Hint:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
