Question

what is the value of (a2-b2)
and what is the value of (a+b)2​

Answer 1

Hi friend,

(1)Now, we will calculate the value of a2+b2. The value of a2+b2 is equal to       4 + 4 = 8. So, a2+b2 = 8.

(2)(a+b)2 equals to (a+b)(a+b). so we will multiply a*a + a*b + b*a + b*b. So if you solve this you will get a2 + 2ab + b2.

Hope this helps!!!!!!!!!

Answer 2

Question :-

• What is the value of $\sf \: ( {a}^{2} - {b}^{2} )$
• What is the value of$\sf {(a + b)}^{2}$

Answer :-

• $\sf \: value \: of \: ( {a}^{2} - {b}^{2} )$
• $\to \: \sf \: \: (a + b)(a - b)$

• $\sf \: value \: of \: {( a + b)}^{2}$
• $\to \: \sf \: {a}^{2} + {b}^{2} + 2ab$
