Find the slop of the tangent to the curve y=(10-sqrt x)(5+sqrt x) at x=25

  • Math please help urgent ! -

    slope**

  • Math please help urgent !- derivative -

    First find the derivative as a product:
    d((10-sqrt x)(5+sqrt x))/dx
    =(10-sqrt(x))((1/2sqrt(x))+(5+sqrt(x))(-1/2sqrt(x))
    =(10-sqrt(x)-5-sqrt(x))/2sqrt(x)
    =(5-2sqrt(x))/2sqrt(x)
    Evaluate dy/dx at x=25
