Maharashtra State Board: Class 12
Definition: Combined Equation
An equation representing two lines together is called the combined (joint) equation of the lines.
Maharashtra State Board: Class 12
Definition: Homogeneous Equation
An equation in which the degree of every term is the same is called a homogeneous equation.
Homogeneous equation of degree 2:
\[ax^2+2hxy+by^2=0\]
Maharashtra State Board: Class 12
Definition: Degree of a Term
The sum of the indices of all variables in a term is called the degree of the term.

Key Points: Nature of Lines
| Condition | Nature |
|---|---|
| \[h^2-ab>0\] | Distinct lines |
| \[h^2-ab=0\] | Coincident lines |
| \[h^2-ab<0\] | Not a pair of lines |
Maharashtra State Board: Class 12
Formula: Slopes of the Lines
If \[ax^2+2hxy+by^2=0\]
Then slopes are:
\[m_1=\frac{-h-\sqrt{h^2-ab}}{b}\]
\[m_2=\frac{-h+\sqrt{h^2-ab}}{b}\]
Their sum is m1 + m2 = \[-\frac{2h}{b}\]
product is m1 m2 = \[\frac{a}{b}\]
Maharashtra State Board: Class 12
Definition: Auxiliary Equation
For \[ax^2+2hxy+by^2=0\]
Slopes of lines are roots of: \[bm^2+2hm+a=0\]
This equation is called the Auxiliary Equation.

Definition: General Second Degree Equation
Equation of the form \[ax^2+2hxy+by^2+2gx+2fy+c=0\], where at least one of a,b,h is not zero, is called a general second degree equation in x and y.
The expression\[abc+2fgh-af^{2}-bg^{2}-ch^{2}\] is the expansion of the determinant \[\begin{vmatrix}
a & h & g \\
h & b & f \\
g & f & c
\end{vmatrix}\]
