1 hours ago The quadratic formula to find the roots of a quadratic equation is: x 1,2 2 – 4ac and is called the discriminant of the quadratic equation. In our question, the equation is x 2 – 9x + 14 = 0. By remembering the form ax 2 + bx + c = 0: a = 1, b = -9, c = 14 So, we can find the discriminant first, and then the roots of the equation: Δ = b 2

4 hours ago Correct answer:-3. Explanation: Given a quadratic equation equal to zero you can factor the equation and set each factor equal to zero. To factor you have to find two numbers that multiply to make 9 and add to make 6. The number is 3. So the factored form of the problem is (x+3) (x+3)=0. This statement is true only when x+3=0.

Frequently Asked Questions

How can i use quadratic equations in real life?

The most common use of the quadratic equation in real world situations is in the aiming of missiles and other artillery by military forces. Parabolas are also used in business, engineering and physics.

How do you calculate quadratic equations?

The Quadratic Formula: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by: For the Quadratic Formula to work, you must have your equation arranged in the form (quadratic) = 0. Also, the 2a in the denominator of the Formula is underneath everything above, not just the square root.

What are quadratic formulas?

A quadratic equation is any polynomial equation of degree 2, or any equation in the form , or any equation that can be expressed in that form. The quadratic formula is a formula for solving any quadratic equation by completing the square on the equation , treating a, b, and c as constants.

What is the quadratic formula?

The standard form of a quadratic equation is ax 2 + bx + c = 0, where a, b are the coefficients, x is the variable, and c is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x 2 is a non-zero term (a ≠0).
