\left(x-40\right)\left(100-2x+120\right)
Use the distributive property to multiply -2 by x-60.
\left(x-40\right)\left(220-2x\right)
Add 100 and 120 to get 220.
220x-2x^{2}-8800+80x
Apply the distributive property by multiplying each term of x-40 by each term of 220-2x.
300x-2x^{2}-8800
Combine 220x and 80x to get 300x.
\left(x-40\right)\left(100-2x+120\right)
Use the distributive property to multiply -2 by x-60.
\left(x-40\right)\left(220-2x\right)
Add 100 and 120 to get 220.
220x-2x^{2}-8800+80x
Apply the distributive property by multiplying each term of x-40 by each term of 220-2x.
300x-2x^{2}-8800
Combine 220x and 80x to get 300x.
