General Form for Linear Expression and Quadratic Expression

General form for linear expression is \(ax+b\), where \(x\) is the variable and \(a\) and \(b\) are constants.

Example: \(4x+7\)

Number of terms: \(2\)

Constant term: \(7\)

Coefficient of \(x\): \(4\)

General form for quadratic expression is \(a{{x}^{2}}+bx+c\), where \(x\) is the variable and \(a\),
\(b\) and \(c\) are constants and \(a\ne 0\).

Example: \(2{{x}^{2}}-x+6\)

Number of terms: \(3\)

Constant term: \(6\)

Coefficient of \(x\): \(-1\)

Coefficient of \({{x}^{2}}\): \(2\)
