Combine fractions in numerator: First, let's combine the fractions in the numerator.((1)/(x+4)−(1)/(4))=(4−(x+4))/((x+4)(4))Simplify the numerator: (4−x−4)/((x+4)(4))=(−x)/((x+4)(4))
Divide simplified numerator by x: Now, divide the simplified numerator by x in the denominator.((x+4)(4))(−x)/(x)=((x+4)(4)x)(−x)
Cancel out x: Simplify the expression by canceling out x.(x+4)(4)x−x=(x+4)(4)−1
Evaluate limit as x approaches 0: Evaluate the limit as x approaches 0.x→0lim((x+4)(4)−1)=(0+4)(4)−1=16−1
