Question

the value of x2 - 1 at x = (-1) is

Answer 1

(-1)2-1= 1-1=0 Answer is 0

Answer 2

ANSWER:

Given:

• $x^2 - 1$

To Find:

• Value at x = -1

Solution:

We are given that,

$\implies x^2 - 1$

Now, to find the value at x = -1, we will substitute the value of x as -1 in the given expression and solve it.

So,

$\implies x^2 - 1$

Substituting x as -1,

$\implies (-1)^2 - 1$

We know that,

$\hookrightarrow (-1)^2 = 1$

So,

$\implies (-1)^2 - 1$

$\implies 1 - 1$

$\implies\bf 0$

Hence, value of $\bf x^2 - 1$ at x = -1 is 0.
