# How do doctors use the quadratic formula?

Doctors use them somehow which you don't need to know.

### Find all complex solutions for the equation x2 equals 4x - 29?

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)) / 2a 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)) / 2a Use the quadratic formula. In x2…

### Two consecutive numbers product is 182.Find them.?

Either use trial and error, or the quadratic formula, solving the following for x: x(x+1)=182 Either use trial and error, or the quadratic formula, solving the following for x: x(x+1)=182 Either use trial and error, or the quadratic formula, solving the following for x: x(x+1)=182 Either use trial and error, or the quadratic formula, solving the following for x: x(x+1)=182

### Why use quadratic formula?

Using the quadratic formula to solve any quadratic equation is the best way of getting around it because the quadratic formula is "the opposite of b plus or minus the square root of b squared minus 4ac all divided by 2a. This formula only works with trinomials and second degree equaitons. If the equation is a binomial, then put in a placeholer (0) and substitute them into the equation.

### What are the conditons that are met before you can use the quadratic formula?

Only that the equation that you are trying to solve is a quadratic, that is to say, the powers of the variable are 2,1 and 0 (or any constant increment of these three numbers). Non-negativity of the discriminant is NOT a condition because you can still use the quadratic formula and get roots that are in the complex domain.

### What is the quadratic formula used for?

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
