Question

write the square of the following experessions (a+1/2)​

Answer 1

Answer:

${a}^{2} + a + \frac{1}{4}$

Step-by-step explanation:

$square \: of \: (a + \frac{1}{2} ) \\ = (a + \frac{1}{2} )^{2} \\ = ( {a})^{2} + 2(a) \frac{1}{2} + ( { \frac{1}{2}) }^{2}$

[ By the formula (a+b)² = a² + 2ab + b², here a = a and b = 1/2. ]

${a}^{2} +( 2 \times a \times \frac{1}{2} ) + {( \frac{1}{2} )}^{2} \\ = {a}^{2} + a + \frac{1}{4}$

hope it helps.

Answer 2

so in this question we use the identity of a^2+b^2+2ab

so a^2+1/4+2×a×1/2

so a^2+1/4+a
