Can a quadratic equation have one solution?

If you get a positive number, the quadratic will have two unique solutions. If you get 0, the quadratic will have exactly one solution, a double root. If you get a negative number, the quadratic will have no real solutions, just two imaginary ones.

What is a quadratic equation with 1 solution?

Solutions And The Quadratic Graph If the graph touches the x-axis at one point then we have one solution. If the graph does not intersect with the x-axis then the equation has no real solution.

Do all quadratic equations have two solutions?

If you answer two to both questions, then every quadratic has two solutions.

How do you make a quadratic equation?

In summary: If you know the vertex and a point on a parabola, use the “vertex-form”, y = a(x – h)2 + k, to write the equation of the parabola. If you know three points on the parabola, but not the vertex, use the form y = ax2 + bx + c to write the equation of the parabola.

What if a quadratic equation has only one real solution?

Answer: If a quadratic equation has exactly one real number solution, then the value of its discriminant is always zero. A quadratic equation in variable x is of the form ax2 + bx + c = 0, where a ≠ 0. Explanation: For example, x2 + 2x + 1 = 0 has only one solution x = -1.

How do you know if a quadratic equation has two solutions?

Solution:

if the discriminant is positive , then the quadratic equation has two solutions.
if the discriminant is equal , then the quadratic equation has one solution.
if the discriminant is negative , then the quadratic equation has no solution.

How do you find an equation given a solution?

To solve for , you must first combine the ‘s on the right side of the equation. This will give you . Then, subtract and from both sides of the equation to get . Finally, divide both sides by to get the solution .

How do you find a quadratic equation?

A quadratic equation is written as #ax^2+bx+c# in its standard form. And the vertex can be found by using the formula #-b/(2a)#. For example, let’s suppose our problem is to find out vertex (x,y) of the quadratic equation #x^2+2x-3# . 1) Assess your a, b and c values. 2) Plug in your values into the formula #-b/(2a)#.

What are the steps to solve the quadratic function?

Now we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a (the coefficient of x 2). Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

What are the types of quadratic equations?

The quadratic equation can be written in three different forms: the standard form, vertex form, and the quadratic form. You can use either form to graph a quadratic equation; the process for graphing each is slightly different.

What is the standard form of quadratic formula?

By Nucreisha Langdon. The standard form of a quadratic equation is y = ax^2 + bx + c, where a, b, and c are coefficiencts and y and x are variables.
