93 {}^{2} + 6 5^{2} - 258 \times 75 {}^{2}
​

 

Answer !

\tt \: 93 {}^{2} + 6 5^{2} - 258 \times 75 {}^{2} =

= ( 93 × 93 ) + 65² – 258 × 75²

= 8.649 + 65² – 258 × 75²

= 8.649 + ( 65 × 65 ) – 258 × 75²

= 8.649 + 4.225 – 258 × 75²

= 8.649 + 4.225 – 258 × ( 75 × 75 )

= 8.649 + 4.225 – 258 × 5.625

= 8.649 + 4.225 – 1.451.250

= 12.874 – 1.451.250

= –1.438.376
