Yes.
But note that if b2 - 4ac is negative, there are no real solutions to the quadratic equation to be found.
When complex numbers are used, this is not a problem as sqrt(-1) = i and so if b2 - 4ac is negative, "sqrt(b2 - 4ac)" becomes "i sqrt(4ac - b2)", meaning the solutions are:
x = -b/2a + i/2a sqrt(4ac-b2)
x = -b/2a - i/2a sqrt(4ac-b2)
By using the quadratic equation formula
How you solve an equation that doesn't factor is to plug a quadratic equation's format; ax2+bx+c into the quadratic formula which is x=-b+square root to (b2-4ac)/2a.
For any quadratic ax2 + bx + c = 0 we can find x by using the quadratic formulae: the quadratic formula is... [-b +- sqrt(b2 - 4(a)(c)) ] / 2a
With great difficulty because it is not a quadratic equation or even a quadratic expression.
Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523
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.
By using the quadratic equation formula
Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?
You convert the equation to the form: ax2 + bx + c = 0, replace the numeric values (a, b, c) in the quadratic formula, and calculate.
a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.
How you solve an equation that doesn't factor is to plug a quadratic equation's format; ax2+bx+c into the quadratic formula which is x=-b+square root to (b2-4ac)/2a.
The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2.
For any quadratic ax2 + bx + c = 0 we can find x by using the quadratic formulae: the quadratic formula is... [-b +- sqrt(b2 - 4(a)(c)) ] / 2a
With great difficulty because it is not a quadratic equation or even a quadratic expression.
It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.
