## What is quadratic function formula?

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. The picture below shows three graphs, and they are all parabolas.

## What is vertex form?

The vertex form of an equation is an alternate way of writing out the equation of a parabola. From this form, it’s easy enough to find the roots of the equation (where the parabola hits the x -axis) by setting the equation equal to zero (or using the quadratic formula).

Answer: Sridhara wrote down rules for Solving Quadratic Equation, hence the most common method of finding the roots of the quadratic equation is recognised as Sridharacharya rule. Because if it equals to zero then the equation will not remain quadratic any more and it will become a linear equation, such as bx + c = 0.

### What are the steps of quadratic formula?

Steps for solving Quadratic application problems:

• Draw and label a picture if necessary.
• Define all of the variables.
• Determine if there is a special formula needed. Substitute the given information into the equation.
• Write the equation in standard form.
• Factor.
• Set each factor equal to 0.

### Who gave the quadratic formula?

The quadratic formula covering all cases was first obtained by Simon Stevin in 1594. In 1637 René Descartes published La Géométrie containing special cases of the quadratic formula in the form we know today.

What is the vertex of the quadratic function?

The vertex of a parabola is the point where the parabola crosses its axis of symmetry. If the coefficient of the x2 term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape.

#### How do you put vertex into standard form?

The standard form of a parabola is y=ax2+bx+c y = a x 2 + b x + c . The vertex form of a parabola is y=a(x−h)2+k y = a ( x − h ) 2 + k ….Lesson Plan.

#### What is quadratic formula also called?

The word “quadratic” comes from “quadratum”, the Latin word for square. Hence, we define a quadratic equation as an equation where the variable is of the second degree. Therefore, a quadratic equation is also called an “Equation of degree 2”.

Who is the father of quadratic equations?

One of his principal achievements in algebra was his demonstration of how to solve quadratic equations by completing the square, for which he provided geometric justifications….Muhammad ibn Musa al-Khwarizmi.
