Question

Is (a+b)^(2)=a^(2)+b^(2)
is (a+b)square is equal to a square + b square

Answer 1

Heya !

No , they are not equal!!

(a+b)² = (a+b) (a+b) or a² + 2ab + b²

while,

a² + b² = (a+b) (a-b)

(a+b)² ≠ a² + b²

Hence, both are not equal

Hope it hlpz...

Answer 2

No,
${(a + b)}^{2}$
and
${a}^{2} + {b}^{2}$
are different...
${(a + b)}^{2} = {(2 + 3)}^{2} = {5}^{2} = 25$
and then
${a}^{2} + {b}^{2} = {2 }^{2} + {3}^{2} = 4 + 9 = 13$
So both are different
