Algebra



For a quadratic equation \(ax^2 +bx +c =0\)

a= coefficient of \(x^2\)
b= coefficient of x
c= constant value of the equation


x = \(\frac{-b ∓ \sqrt{b^{2}- 4ac}}{2a}\)

Let the two roots of the equation be \(\alpha\) & \(\beta\) then ,

\(\alpha\) + \(\beta\) = \(\frac{-b}{a}\)

\(\alpha*\beta\) = \(\frac{c}{a}\)



Exponents



\(0^{n}\) = 0

\(1^{n}\) = 1

\(x^{0}\) = 1

\(x^{1}\) = x

\(x^{-n}\) = \(\frac{1}{x}\)

\(x^{m}*x^{n}\) = \(x^{m+n}\)

\(\frac{x^{m}}{x^{n}}\) = \(x^{m-n}\)

\((x^{m})^{n}\) = \(x^{m*n}\)

\((\frac{x}{y})^{n}\) = \(\frac{x^{n}}{y^{n}}\)
