$2x^{-2}=-\left(-7x^{-1}-15\right)$
Learn how to solve equazioni e funzioni radicali problems step by step online. Solve the equation with radicals 2x^(-2)-7x^(-1)+-15=0. Apply the formula: x+a=b\to x=b-a, where a=-7x^{-1}-15, b=0, x+a=b=2x^{-2}-7x^{-1}-15=0, x=2x^{-2} and x+a=2x^{-2}-7x^{-1}-15. Apply the formula: -\left(a+b\right)=-a-b, where a=-7x^{-1}, b=-15, -1.0=-1 and a+b=-7x^{-1}-15. Apply the formula: x^a=\frac{1}{x^{\left|a\right|}}. Move everything to the left hand side of the equation.
