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.
The quadratic formula can only be used to solve equations of degree 2, which means it is applicable specifically to quadratic equations of the form ( ax^2 + bx + c = 0 ). If a term in the equation has a degree higher than 2, such as in cubic or quartic equations, the quadratic formula is not applicable. In those cases, other methods or formulas must be used to find the solutions.

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.

Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
1+1=2
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
