Answer:
q 2
Step-by-step explanation:
The square root of 998 in mathematical form is written with the radical sign like this √998. We call this the square root of 998 in radical form. The square root of 998 is a quantity (q) that when multiplied by itself will equal 998.
√998 = q × q = q 2
Answer:
Step-by-step explanation:
To convert an equation into standard form, we want to get into the form 
.
If we have 
, our first step is to get the x term on the left side. We can do this by subtracting 3x from both sides.
I find it easier now to just divide both sides by -1, so that we have a more consistent equation.
Hope this helped!
