Question

HHloo pls help me to solve this ❤️​​

Answer 1

$\huge\red{ANSWER:}$

(i)

$(a + b) ^{2} = (a + b) \times (a + b)$

By distributive property →

$= a \times (a + b) + b \times (a + b)$

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

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

(ii)

$(a - b) ^{2} = (a - b) \times (a - b)$

By distributive property →

$= a \times (a - b) - b \times (a - b)$

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

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

AND THAT'S OUR ANSWER!!!
