225=17^{2}-\left(10-2\right)^{2}
Calculate 15 to the power of 2 and get 225.
225=289-\left(10-2\right)^{2}
Calculate 17 to the power of 2 and get 289.
225=289-8^{2}
Subtract 2 from 10 to get 8.
225=289-64
Calculate 8 to the power of 2 and get 64.
225=225
Subtract 64 from 289 to get 225.
\text{true}
Compare 225 and 225.
