Evaluate Using the Given Value h-(h^2-1)÷2 ; h=-1

$h - (h^{2} - 1) \div 2$ ; $h = - 1$

Step 1

Replace the variable $h$ with $- 1$ in the expression.

$(- 1) - ({(- 1)}^{2} - 1) \div 2$

Step 2

Simplify each term.

Rewrite the division as a fraction.

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

Simplify the numerator.

Raise $- 1$ to the power of $2$ .

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

Subtract $1$ from $1$ .

$- 1 - \frac{0}{2}$

Divide $0$ by $2$ .

$- 1 - 0$

Multiply $- 1$ by $0$ .

$- 1 + 0$

Step 3

Add $- 1$ and $0$ .

$- 1$
