Question

someone help

Answer 1

set it up normally and mutliply by the complex conjugate

\[\frac{14\sqrt{x+h}-14\sqrt{x}}{h}\cdot \frac{14\sqrt{x+h}+14\sqrt{x}}{14\sqrt{x+h}+14\sqrt{x}}\] Note that you can factor out a 14 from the get go

Answer 2

\[14\cdot \frac{(x+h)-x}{\sqrt{x+h}+\sqrt{x}}\]

Answer 3

\[\frac{14h}{\sqrt{x+h}+\sqrt{x}}\]

Answer 4

and thats it? @freewilly922
