Diffrence of sqaures

2. pooja195

$\huge~\rm~\sqrt{x^2}-\sqrt{16}$

3. pooja195

Then once you have that put it into this form (a+b)(a-b) replacing the letters with the info from the problem

You could have said that lol whats the sqrt of 16?

12. OregonDuck

x²-16 should be easily spotted as the difference of two squares so square root 16 and x so you get x+4 then you have one other set of brackets to give -16 and 0 x's difference of two squares it the same numbers different signs so for example|dw:1439562043024:dw|
