Here, we show you a step-by-step solved example of quadratic formula. This solution was automatically generated by our smart calculator:
Find the roots of the equation using the Quadratic Formula
Factor the trinomial $x^2+6x+8$ finding two numbers that multiply to form $8$ and added form $6$
Rewrite the polynomial as the product of two binomials consisting of the sum of the variable and the found values
Break the equation in $2$ factors and set each factor equal to zero, to obtain simpler equations
Solve the equation ($1$)
We need to isolate the dependent variable $x$, we can do that by simultaneously subtracting $2$ from both sides of the equation
Canceling terms on both sides
Solve the equation ($2$)
We need to isolate the dependent variable $x$, we can do that by simultaneously subtracting $4$ from both sides of the equation
Canceling terms on both sides
Combining all solutions, the $2$ solutions of the equation are
