Which one is the quadratic equation answer?

Answer: A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

What are the correct order of the 4 steps we use to solve a quadratic function using factoring?

To solve an quadratic equation using factoring :

  1. 1 . Transform the equation using standard form in which one side is zero.
  2. 2 . Factor the non-zero side.
  3. 3 . Set each factor to zero (Remember: a product of factors is zero if and only if one or more of the factors is zero).
  4. 4 . Solve each resulting equation.

What is the correct quadratic formula?

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .

What are 4 examples of quadratic equation?

Examples of Quadratic Equations in Other Forms x(x – 2) = 4 [upon multiplying and moving the 4, becomes x² – 2x – 4 = 0] x(2x + 3) = 12 [upon multiplying and moving the 12, becomes 2x² – 3x – 12 = 0] 3x(x + 8) = -2 [upon multiplying and moving the -2, becomes 3x² + 24x + 2 = 0]

What is the example of quadratic function?

Quadratic Function Examples The quadratic function equation is f(x) = ax2 + bx + c, where a ≠ 0. Let us see a few examples of quadratic functions: f(x) = 2×2 + 4x – 5; Here a = 2, b = 4, c = -5. f(x) = 3×2 – 9; Here a = 3, b = 0, c = -9.
