The 'x' from the expression (x² - 3x - 4 < 0) lies between the interval -1 and 4

Step-by-step explanation:

Given Data

Find in which interval 'x' lies in an expression x² - 3x - 4 < 0

The given expression (x² - 3x - 4) is in the form of quadratic equation.

We can solve the quadratic equation as follows

x² - 3x - 4 < 0

=> x² - 4x + x - 4 < 0

=> x ( x- 4) + 1 (x-4) < 0

=> ( x- 4) , (x + 1) < 0

=> ( x- 4) < 0  

=>  x = 4  

And , => ( x + 1) < 0  

=>  x = -1

Therefore for an expression (x² - 3x - 4 < 0) the value of 'x' lies between the interval -1 and 4
