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
