Question

factorize (a+b)^2 - 4ab using appropriate identity​

Answer 1

$\LARGE{\underline{\underline{\boxed{\sf{\purple{Answer}}}}}}$

${ \large\mathtt{\blue{(a + b) {}^{2} - 4ab}}} \\ { \large\mathtt{\blue{a {} ^{2} + b {}^{2} + 2ab - 4ab }}} \\ { \large\mathtt{\blue{a {}^{2} + b {}^{2} - 2ab }}} \\ { \large \underline \mathtt{\blue{(a - b) {}^{2} }}}$

Iᴅᴇɴᴛɪᴛɪᴇs ᴜsᴇᴅ :-

${ \large\mathtt{ \green{ (a + b) {}^{2} = a {}^{2} + 2ab + b {}^{2} }}} \\ { \large\mathtt{\green{(a - b) {}^{2} = a {}^{2} - 2ab + b {}^{2} }}}$
