Question

what the formula of

(a+b)²​

Answer 1

${a}^{2} + 2ab + {b}^{2}$

Answer 2

Answer:

$\: \: \sf \rightarrow \: {(a + b)}^{2} = {(a)}^{2} + {(b)}^{2} + 2ab$

where,

• a is the first term.
• b is the second term.

Additional Information:

$\: \sf \: {(a - b)}^{2} = {a}^{2} + {b}^{2} - 2ab$

$\: \sf \: { ({a}^{2} + {b}^{2} ) }^{2} = {(a + b)}^{2} - 2ab$

$\: \sf \: {( {a}^{2} - {b}^{2} ) }^{2} = (a + b)(a - b)$
