how would you simplify this equation:

y = (x+3)/[(4-sqrt(16+h))]

please help me!

you have three variables. I am not certain "simplify" is an appropriate term here.

ohhhh it was my mistake. I meant:

y = h/[(4-sqrt(16+h))]

y = h/[(4-sqrt(16+h))]

rationalize the denominator..

y = h/[(4-sqrt(16+h))] *(4+sqrt(16+h)/(4+sqrt(16+h)

y=h(4+sqrt(16+h)/(16-16-h)

you finish it. check my work.
