As you probably suspect, there are no non-mathematical situations in which you would use the quadratic formula.

I suggest you use the quadratic formula.

One would use the quadratic formula for solving binomials that are otherwise hard to factor. You can find both real and imaginary solutions using this method, making it highly superior to factoring in this regard.

Simply learn and use the quadratic equation formula.

By using the quadratic equation formula or by completing the square

The question is based on the false assumption that the quadratic formula is not used in daily life. Wrong, it IS!

All types of engineering professions use the quadratic formula since it applies to ordinary differential equations.

A quadratic function is ax2+bx+c You can solve for x by using the quadratic formula, which, as the formula requires the use of square roots, would be tricky to put here.

You convert the equation to the form: ax2 + bx + c = 0, replace the numeric values (a, b, c) in the quadratic formula, and calculate.

True

By knowing how to use the quadratic equation formula.

Use the quadratic formula. In x2 - 4x + 29 = 0, a is 1, b is -4, c = 29. The quadratic formula is: x = (-b plusminus squareroot(b2 - 4ac)) / 2aUse the quadratic formula. In x2 - 4x + 29 = 0, a is 1, b is -4, c = 29. The quadratic formula is: x = (-b plusminus squareroot(b2 - 4ac)) / 2aUse the quadratic formula. In x2 - 4x + 29 = 0, a is 1, b is -4, c = 29. The quadratic formula is: x = (-b plusminus squareroot(b2 - 4ac)) / 2aUse the quadratic formula. In x2 - 4x + 29 = 0, a is 1, b is -4, c = 29. The quadratic formula is: x = (-b plusminus squareroot(b2 - 4ac)) / 2a

Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.

No.

in most engineering jobs

All you do is set the quadratic function to equal to 0. Then you can either factor or use the quadratic formula to solve for your unknown variable.

the formula you are going to use to answer the equation

In problems of motion, especially involving constant acceleration, a quadratic equation will from the formulas of motion to solve for time, usually. This is just one example.

It all depends on what calculator you use to know how to program the formula into it.
