Question

Simplify (4a +3b) ² - (4a -3 b) ² +48ab​

Answer 1

Answer:

we know the formula (a +b)^2= a^2 + b^2 + 2ab

therefore ,

= (4a +3b) ² - (4a -3 b) ² +48ab​

= (4a + 3b - (4a-3b)) ^2

= (6b)^2

=36b^2

Answer 2

${\huge {\underline {\red {\mathcal {Answer}}}}}$

= (4a +3b) ² - (4a -3 b) ² +48ab

= (4a +3b) ² - 4a + 3b² - 48ab

= (a +6b)² - 48ab

= (-47a7b)²
