FAQs

How do you check the answers to a quadratic equation? ›

Check your answers to a quadratic equation by reworking them into the original equation and seeing if they equal 0. Write the quadratic equation and the roots that you calculated. For example, let the equation be x² + 3x + 2 = 0, and the roots be -1 and -2. Substitute the first root into equation and solve.

Does the quadratic formula give 2 answers? ›

As we have seen, there can be 0, 1, or 2 solutions to a quadratic equation, depending on whether the expression inside the square root sign, (b [ 2 ] - 4ac), is positive, negative, or zero. This expression has a special name: the discriminant.

How many answers do you expect to get for a quadratic equation? ›

Quadratic equation may have infinitely many solutions. But only two roots or zeros. Because we can put any random value of x(x belongs to R), we can get corresponding value of y.

Which one is the quadratic equation answer? ›

Answer: The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: y = x^2 + 3x + 1.

How to solve quadratic? ›

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) . See examples of using the formula to solve a variety of equations.
