x^2 -8x-4=0
x=[8±√(64+16)]/2
x=(8±4√5)/2
x=4±2√5
The Quadratic formula in mathematics is used to solve quadratic equations in algebra. The simplest way to solve these equations is to set each of the factors to zero and then solve each factor separately.
Solve using the quadratic formula

-2x2 + 9x - 12 = 0Then apply the quadratic formula.
Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523
The Quadratic formula in mathematics is used to solve quadratic equations in algebra. The simplest way to solve these equations is to set each of the factors to zero and then solve each factor separately.
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.

Graphically might be the simplest answer.
The quadratic formula is used all the time to solve quadratic equations, often when the factors are fractions or decimals but sometimes as the first choice of solving method. The quadratic formula is sometimes faster than completing the square or any other factoring methods. Quadratic formula find: -x-intercept -where the parabola cross the x-axis -roots -solutions
If you can't factor it easily, use the quadratic formula.
