## Is there a negative quadratic equation?

It has the general form: 0 = ax2 + bx + c Each of the constant terms (a, b, and c) may be positive or negative numbers. Since nothing can exist as a negative concentration, the other answer must be the RIGHT one. Let’s work through a typical quadratic calculation that you might find in equilibrium problems.

### What is the square of negative 25?

five

The square root of 25 is equal to five. And as already stated, the square root of negative one is equal to 𝑖. This means that the square root of negative 25 is equal to five 𝑖.

#### How do you calculate the quadratic equation?

A quadratic equation is written as #ax^2+bx+c# in its standard form. And the vertex can be found by using the formula #-b/(2a)#. For example, let’s suppose our problem is to find out vertex (x,y) of the quadratic equation #x^2+2x-3# . 1) Assess your a, b and c values. In this example, a=1, b=2 and c=-3.

**Why do you use square roots to solve quadratic equations?**

A benefit of this square-rooting process is that it allows us to solve some quadratics that we could not have solved before when using only factoring. For instance: Solve x2 – 50 = 0. This quadratic has a squared part and a numerical part.

**What are the roots of the quadratic equation 0?**

The number of roots of a polynomial equation is equal to its degree. Hence, a quadratic equation has 2 roots. Let α and β be the roots of the general form of the quadratic equation :ax 2 + bx + c = 0. We can write: α = (-b-√b 2 -4ac)/2a and β = (-b+√b 2 -4ac)/2a Here a, b, and c are real and rational.

## What is the square root of a quadratic function?

The square root principle is a technique that can be used to solve quadratics, but in order to solve a quadratic using the square root principle the problem must be in the correct form. To solve a quadratic using the square root principle the quadratic must be in vertex form, a(x – h)2 + k.
