(c) {a}^{2} +a b+{b}^{2}
(d) {a}^{2}-a b+{d}^{2}​

Answer 1

Answer:

(D)

Step-by-step explanation:

$\blue{ \bf{ QUESTIONS \: : - \: }}$

Value of a²-b²:-

(a)(a+b) (a+b)

(b) (a-b) (a+b)

(c) a²+2 a b+b²

(d) a²-2ab + b²

________________________________

$\bigstar{ \pink{ \bf{ \underline{ \underline{Requried \: ANSWER \: : - }}}}}$

$\bf{ (a - b) \: (a - b)}$

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

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