Solve (-3x^-2)(-3x)^2 + 3 - x^0

Evaluate

(- 3 x^{- 2}) (- 3 x)^{2} + 3 - x^{0}

To find the roots of the expression,set the expression equal to 0

(- 3 x^{- 2}) (- 3 x)^{2} + 3 - x^{0} = 0

Find the domain

(- 3 x^{- 2}) (- 3 x)^{2} + 3 - x^{0} = 0, x \neq = 0

Calculate

(- 3 x^{- 2}) (- 3 x)^{2} + 3 - x^{0} = 0

Remove the parentheses

- 3 x^{- 2} (- 3 x)^{2} + 3 - x^{0} = 0

Multiply the terms
