Hi Shahad,

Just wanted to explain Keith's answer to part B if you did not understand it. He is saying that by squaring both sides of the equation, you can prove it is true. That is, the left side has a square root function so it does not need to be squared, but when you square the other side, the equations will match up. Alternatively, you can just show that the square root of x^{4}+8x^{2}+16 is x^{2}+4. Hope this helps!

Best,

Harsh

Hello Keith, Thank you for this! But for part B, it's a square root of (x^4+8x^2+16) Sorry about that.08/27/20
