WebNow we can determine the solution by looking at the graph we just plotted. Our inequality was x^2 +4x -5 > 0. We know that in x = -5 and x = 1 the expression is equal to zero. We must have that the expression is larger than zero and therefore we need the regions left from the smallest root and right of the largest root. Our solution will then be: WebTo solve your inequality using the Inequality Calculator, type in your inequality like x+7>9.
