Put the terms in order of decreasing degree, all on the left. When convenient, it is nice to have mutually prime integer coefficients with the leading one positive.
a) x² -2x +1 = 0
b) x² +15 = 0
c) 4x² -12 = 0
or, better, divide out the common factor of 4.
x² -3 = 0
d) 3x² -x -5 = 0
_____
Shown is the standard form for a single-variable second-degree equation. Form varies depending on the nature of the equation. Equations of conic sections have different standard forms, depending on the curve.
Answer:
The equation for the following graph:
Step-by-step explanation:
- You first need to find the slope by using the <u>slope formula</u>:
(where 
is the first point and 
is the second point)
-Use the given points 
and 
from the graph for the formula:
Then, you solve:
After you have found the slope, use the slope 
and the first point for the <u>point-slope formula:</u>
<u>(</u>where 
is the slope and 
is the first point)
Then, you solve:
So, the equation for the following graph is .
Answer:
4:6 or 2:3
Step-by-step explanation:
Since the ratio of mass of oxygen to carbon is 4:3, when there are two carbons the ratio will be 4:3*2=4:6=2:3. Hope this helps!
