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

Answer:

The value of the expression for a = 1\2 and b =-1\2 is $\frac{-1}{4}$.

Step-by-step 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.

$(\frac{1}{2})^2 + \frac{-1}{2}$

Solve the above expression as shown:

$\frac{1}{4} +\frac{-1}{2}$

$\frac{1-2}{4}$

$\frac{-1}{4}$

Hence, the value of the expression for a = 1\2 and b =-1\2 is $\frac{-1}{4}$.
