Answer:
x²(1-
)
Step-by-step explanation:
Each side of the cookie dough is x long, since there is no given number, the diameter of the plate is also x, its as long as the square is wide, making the radius 1/2x.
The area of the cookie dough is x², the area of the plate is 1/4
x².
You have the equation x²- 
x²the equation has a Greatest Common Factor of x² so your factored equation is x²(1-
)
Let i = sqrt(-1) which is the conventional notation to set up an imaginary number
The idea is to break up the radicand, aka stuff under the square root, to simplify
sqrt(-8) = sqrt(-1*4*2)
sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)
sqrt(-8) = i*2*sqrt(2)
sqrt(-8) = 2i*sqrt(2)
