$2x^{-2}=-\left(-7x^{-1}-15\right)$
Learn how to solve equations problems step by step online. Solve the equation with radicals 2x^(-2)-7x^(-1)+-15=0. We need to isolate the dependent variable x, we can do that by simultaneously subtracting -7x^{-1}-15 from both sides of the equation. Simplify the product -(-7x^{-1}-15). Applying the property of exponents, \displaystyle a^{-n}=\frac{1}{a^n}, where n is a number. Move everything to the left hand side of the equation.
