Expand ${(a + 5)}^{2}$ using appropriate identity

Using, the identity $(x + y)^{2} = x^{2} + y^{2} + 2 x y$ .

Given, $(a + 5)^{2}$ we apply the above identity as follows:

$(a + 5)^{2} = a^{2} + 5^{2} + (2 \times a \times 5) = a^{2} + 25 + 10 a$

Hence, $(a + 5)^{2} = a^{2} + 10 a + 25$ .

Expand (a+5)2 using appropriate identity

Using, the identity (x+y)2=x2+y2+2xy.Given, (a+5)2 we apply the above identity as follows:(a+5)2=a2+52+(2×a×5)=a2+25+10aHence, (a+5)2=a2+10a+25.

Expand ${(a + 5)}^{2}$ using appropriate identity

Using, the identity $(x + y)^{2} = x^{2} + y^{2} + 2 x y$ .

Given, $(a + 5)^{2}$ we apply the above identity as follows:

$(a + 5)^{2} = a^{2} + 5^{2} + (2 \times a \times 5) = a^{2} + 25 + 10 a$

Hence, $(a + 5)^{2} = a^{2} + 10 a + 25$ .
