The value of the expression when x is 4 is 0

An algebraic fraction is a ratio of two algebraic expressions, typically polynomials.

It involves variables, constants, and mathematical operations.

Finding the value of the expression x² - 16)/x -4

when x = 4

we substitute 4 for x in the expression.

= 4² - 16)/4-4

= 16-16)/4-4

= 0/0

= 0

Therefore the value of the expression when x is 4 is 0
