Why is the quadratic formula better than factoring?

The quadratic formula may also demonstrate when no solution exists (something that is difficult to see with factoring). Quadratics which arise from observed measurements and experimental results are more likely to need the use of the quadratic formula for solving.

Can you use the quadratic formula instead of factoring?

Be sure that your equation is in standard form (ax2+bx+c=0) before you start your factoring attempt. Finally, the quadratic formula will work on any quadratic equation. However, if using the formula results in awkwardly large numbers under the radical sign, another method of solving may be a better choice.

How is solving a quadratic equation different from factoring?

Therefore, when solving quadratic equations by factoring, we must always have the equation in the form “(quadratic expression) equals (zero)” before we make any attempt to solve the quadratic equation by factoring. Note that “x = 3, 4” means the same thing as “x = 3 or x = 4”; the only difference is the formatting.
