720\pi +12^{2}\pi =864\pi
Multiply 24 and 30 to get 720.
720\pi +144\pi =864\pi
Calculate 12 to the power of 2 and get 144.
864\pi =864\pi
Combine 720\pi and 144\pi to get 864\pi .
864\pi -864\pi =0
Subtract 864\pi from both sides.
0=0
Combine 864\pi and -864\pi to get 0.
\text{true}
Compare 0 and 0.
