Answer 2

To evaluate : $98^{2} - 88^{2}$

Solution :  

• To evaluate  the given expression $98^{2} - 88^{2}$  we apply identity , $a^{2} - b^{2} = ( a + b) ( a- b)$
• Here , $a = 98$ and $b = 88$
• Therefore , $98^{2} - 88^{2} = ( 98 + 88 ) ( 98 - 88 )$

                                           $= 186 \times 10 \\= 1860$  

Hence , on evaluating $98^{2} - 88^{2}$  we get , $1860$ as answer .
