Question

Find x²-1, if the value of x is 12

Answer 1

In the above question given that

Given the equation $X^{2} -1$

We have determine the given equation

we are solving the problem  consider the given expression

$X^{2} -1$

When putting  the value of $X=12$

$X^{2} -1\\(12^{2})-1\\144-1\\143$

Hence the value $X^{2} -1$ will be$143$

Answer 2

Answer:

=> The value of $x^2-1$ is 143.

Step-by-step explanation:

Given that:-

$x^2-1$

Also, x is given as 12.

To find:- The value of $x^2-1$,

Now, substitute the value of x as 12 in the given equation:

As we have,

=> $x^2-1$

=> $(12)^2-1$

By further calculation, we get

=> 144 - 1

Subtract both the terms, we get

=> 143

Hence, the required solution is 143.
