Full Answer

Every online algebra solver is different. For Mathway, you directly type in the equation to be solved in the white text area and then press the blue button "Answer." For instance, to solve the equation x^2 + 7 = 15, type in the equation as it is, then press the blue button "Answer." The software is intelligent enough to realize it needs to use the quadratic formula to solve for x.

For the particular example, both solvers should yield plus or minus the square root of 2 multiplied by 2.
