## What is quadratic equation explain?

Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is: ax² + bx + c = 0. where x is an unknown variable and a, b, c are numerical coefficients.

## What is quadratic equation and give examples?

In math, we define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. 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. y = x^2.

## What is a quadratic equation and what is not?

These values are called the solutions of the equation. Linear equations that are written in the standard form , ax + b = 0, a ≠ 0, have one solution. Quadratic equations may have no solutions, one solution, or, as in the above example, two solutions.

What is a quadratic equation? A polynomial which has the highest degree equal to two is a quadratic equation which is expressed in the form of ax+bx+c=0, where x is the variable and a,b,c are the real numbers & a ≠ 0.

## What are the 4 ways to solve a quadratic equation?

It's negative B divided by 2a. So this is a B and C. So the opposite of B is going to be positive 2MoreIt's negative B divided by 2a. So this is a B and C. So the opposite of B is going to be positive 2 over 2 times a which you can see is 1 2 divided by 2 is 1 that's the x-coordinate of our vertex.

## What are the 5 examples of quadratic equation?

Examples of the standard form of a quadratic equation (ax² + bx + c = 0) include:

• 6x² + 11x - 35 = 0.
• 2x² - 4x - 2 = 0.
• -4x² - 7x +12 = 0.
• 20x² -15x - 10 = 0.
• x² -x - 3 = 0.
• 5x² - 2x - 9 = 0.
• 3x² + 4x + 2 = 0.
• -x² +6x + 18 = 0.
