Question

identites use of for mules too solve the given sum (a+½)²​

Answer 1

Step-by-step explanation:

we know the identity,

(a+b)^2=a^2+2ab+b^2

then

(a+1/2)^2=a^2+2×a×(1/2)^2

= a^2+a+(1/4)

therefore by multiplying whole equation by 4

we get,

4a^2+4a+1=0

now solving the equation we will get the value of a.
