When you graph the quadratic equation, you have three possibilities...
1. The graph touches x-axis once. Then that quadratic equation only has one solution and you find it by finding the x-intercept.
2. The graph touches x-axis twice. Then that quadratic equation has two solutions and you also find it by finding the x-intercept
3. The graph doesn't touch the x-axis at all. Then that quadratic equation has no solutions. If you really want to find the solutions, you'll have to go to imaginary solutions, where the solutions include negative square roots.
Draw the graph of the equation. the solution is/are the points where the line cuts the x(horisontal) axis .
Whether or not that there is a solution to a quadratic equation,
To find the solution to this equation, you need to rearrange the terms and solve for the variable. 4 = 2b + b^2 can be rewritten as b^2 + 2b - 4 = 0. You can then solve this quadratic equation by factoring, completing the square, or using the quadratic formula.
There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.

Graph the equation then find the x intercepts.

Write an algorithm to find the root of quadratic equation
y=2x2 + 3x-1 To find the zeros of this equation (when y=0) set the equation = 0 0=2x2 + 3x-1 Now, you can either graph the equation in a graphing calculator and find the x intercepts (where the function crosses the x-axis and y=0) or you can factor the quadratic equation by "smiling" or reverse foiling. However, this equation cannot be easily factored. Therefore, using a graphing calculator will provide the correct answer of x= -1.780776 and x= 0.28077641 You can also use the quadratic formula where the general form of a quadratic equation is ax2 +bx+ c=0=y In order to use the quadratic formula, you simple plug the corresponding values into the x= equation. This will produce the same results as graphing and finding the x intercepts.

The general form of a quadratic equation is ax^2+bx+c=0. The quadratic formula is used to find the x intercepts of a parabola. It goes like this: x=(-b+or-the (square root of b^2-4ac))/2a. With a specific equation you plug the values for a, b, and c into the formula. It is best to use a graphing calculator. Hope this helps.
You write the equation in such a way that you have zero on the right side. Then you graph the expression on the left side of the equal sign, and check where it touches the x-axis. Note that this method works for most common equations.

No, the quadratic equation, is mainly used in math to find solutions to quadratic expressions. It is not related to science in any way.
