What is the value of the discriminant of the quadratic equation − 2×2 − 8x 8 and what does its value mean about the number of real number solutions the equation has?
What is the value of the discriminant of the quadratic equation −2×2 = −8x + 8, and what does its value mean about the number of real number solutions the equation has? The discriminant is equal to 0, which means the equation has one real number solution.
What are the steps to the quadratic formula?
Now we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a (the coefficient of x2). 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 is the value of the discriminant of the quadratic equation and what does its value mean about the number of real number solutions the equation has?
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. If it’s less than 0, there are no solutions. If it’s equal to 0, there is one solution.
What is the first step to solving?
The first step in effective problem-solving is to identify the real problem you are trying to solve. Rarely is the presenting problem the real problem. If employees are not following a procedure, chances are good the problem is not with the employee.
How do you complete a square with two variables?
Strategies for completing the square – Circles:Move all terms containing x x x and y y y to one side, and the constant term (if there is) to the other side.Divide the equation by the coefficient of x x x and y y y if it’s different from one.Complete the square in x x x and y y y.Rearrange and identify its elements.
How do you simplify quadratic equations?
Completing the squarePut the equation into the form ax 2 + bx = – c.Make sure that a = 1 (if a ≠ 1, multiply through the equation by. before proceeding).Using the value of b from this new equation, add. Find the square root of both sides of the equation.Solve the resulting equation.
What is a discriminant formula?
Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax2 + bx + c = 0, the discriminant is b2 − 4ac; for a cubic equation x3 + ax2 + bx + c = 0, the discriminant is a2b2 + 18abc − 4b3 − 4a3c − 27c2.
What happens when the discriminant is 0?
The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A discriminant of zero indicates that the quadratic has a repeated real number solution. A negative discriminant indicates that neither of the solutions are real numbers.
How do you use the discriminant to determine the number of real solutions?
The discriminant is the expression b2 – 4ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has. If you get a positive number, the quadratic will have two unique solutions.
What are the 4 ways to solve quadratic equations?
The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
Why do we solve quadratic equations?
The equation is used to find shapes, circles, ellipses, parabolas, and more. It also used to design any object that has curves and any specific curved shape needed for a project. The military uses the quadratic equation when they want to predict where artillery shells hit the earth or target when fired from cannons.
