225-4\times 2\left(32-x\right)=0
Calculate 15 to the power of 2 and get 225.
225-8\left(32-x\right)=0
Multiply 4 and 2 to get 8.
225-256+8x=0
Use the distributive property to multiply -8 by 32-x.
-31+8x=0
Subtract 256 from 225 to get -31.
8x=31
Add 31 to both sides. Anything plus zero gives itself.
x=\frac{31}{8}
Divide both sides by 8.
