Y= (Square root of x) - 2 ________________________ (square root of x) + 2 Calculate dy/dx Please help, thank you
by the quotient rule dy/dx = [ (x^(1/2) + 2)( (1/2)x^(-1/2) - (x^(1/2)- 2)((1/2)x^(-1/2) ] / (√x+2)^2 = (1/2)x^(-1/2) [ x^(1/2 + 2 - x^(1/2) + 2]/(√x+2)^2 = (1/2)(1/√x)(4)/(√x+2)^2 = 2/(√x(√x+2)^2 )
