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:
point, line, plane
Step-by-step explanation:
none of these can be defined exactly
3O=12/3 Divide both sides by 3.
/3
O=4

2(4)+18=2∆
8+18=2∆
26=2∆
/2 /2 Divide by 2
∆=13
