Question

Evaluate a2 + b for a = 1\2 and b =-1\2.

Answer 1

The answer is 1/4 + - 1/2, which equals -1/4 as the answer.

Answer 2

The value of the expression for a = 1\2 and b =-1\2 is
`(-1)/(4)`.

Explanation:

Consider the provided expression.

`a^2 + b`

We need to solve the value of expression for a = 1\2 and b =-1\2.

Substitute the value a and b in the provided expression.

`((1)/(2))^2 + (-1)/(2)`

Solve the above expression as shown:

`(1)/(4) +(-1)/(2)`

`(1-2)/(4)`

`(-1)/(4)`

Hence, the value of the expression for a = 1\2 and b =-1\2 is
`(-1)/(4)`.
