How do you solve #8x^2+ 7 = 9x^2+ 10#? Algebra Quadratic Equations and Functions Comparing Methods for Solving Quadratics 1 Answer flaxar · Stefan V. Nov 9, 2015 #8x^2 + 7 = 9x^2 + 10# #8x^2 -9x^2 = 10 - 7# #-x^2 = 3# #x^2 = -3# #x = sqrt3# Explanation: first, you separate and move the number to the other side and #x^2# to the other side. then solve it. #x^2# when we bring to the other side will become square root. :) Answer link Related questions What are the different methods for solving quadratic equations?
