WebPurplemath. To be honest, solving "by graphing" is a somewhat bogus topic. The basic idea behind solving by graphing is that, since the (real-number) solutions to any equation (quadratic equations included) are the x-intercepts of that equation, we can look at the x-intercepts of the graph to find the solutions to the corresponding equation.However, there …
WebAfter doing so, solve for x x as usual. The final answers are {x_1} = 1 x1 = 1 and {x_2} = - {2 \over 3} x2 = −32.
