# What What Is Quadratic Equation

Posted on

If you are looking for the answer of what what is quadratic equation, you’ve got the right page. We have approximately 10 FAQ regarding what what is quadratic equation. Read it below.

a quadratic equation has an expontent 2

example: x²+20x+25

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared

It means that when a Term is squared it is considered a quadratic equation, on the other hand A term that exceeds or does not include a degree isn’t considered as a quadratic equation

## The roots of a quadratic equation are -8 and -10.what

The roots of a quadratic equation are -3 and -15 .what is its quadratic equation​

Step by step explanation:

x=-8

x+8=-8+8

(x+8)

x=-10

x+10=-10+10

(x+10)

therefore,(x+8)(x+10) are the factors

Expand the following:

(x + 8) (x + 10)

(x + 8) (x + 10) = (x) (x) + (x) (10) + (8) (x) + (8) (10):

x x + 10 x + 8 x + 8 10

x x = x^2:

x^2 + 10 x + 8 x + 8 10

8×10 = 80:

x^2 + 10 x + 8 x + 80

Grouping like terms, x^2 + 10 x + 8 x + 80 = x^2 + (10 x + 8 x) + 80:

x^2 + (10 x + 8 x) + 80

10 x + 8 x = 18 x:

the equation is

x^2 + 18 x + 80

x=-3

x+3=-3+3

(x+3)

x=-15

x+15=-15+15

(x+15)

therefore,(x+3)(x+15) are the factors

Expand the following:

(x + 3) (x + 15)

(x + 3) (x + 15) = (x) (x) + (x) (15) + (3) (x) + (3) (15):

x x + 15 x + 3 x + 3 15

x x = x^2:

x^2 + 15 x + 3 x + 3 15

3×15 = 45:

x^2 + 15 x + 3 x + 45

Grouping like terms, x^2 + 15 x + 3 x + 45 = x^2 + (15 x + 3 x) + 45:

x^2 + (15 x + 3 x) + 45

15 x + 3 x = 18 x:

The equation is

x^2 + 18 x + 45

if the equation has no degree of 2

Step-by-step explanation:

a quadratic equation has a degree of 2 while a non quadratic equation doesn’t have a degree of 2

## – What is Quadratic Equation? – What is the degree

– What is the degree of Quadratic Equation?​

The degree of a quadratic equation is 2. A quadratic equation is defined as a polynomial equation.

Step-by-step explanation:

Examples of quadratic equations are: 6x² + 11x – 35 = 0, 2x² – 4x – 2 = 0, 2x² – 64 = 0, x² – 16 = 0, x² – 7x = 0, 2x² + 8x = 0 etc. From these examples, you can note that, some quadratic equations lack the term “c” and “bx.”

You can tell that a certain type of equation is quadratic or not by looking at the degree of the equation. This is the highest exponent. In a quadratic equation the highest degree must 2 otherwise it is not quadratic.

Example:

x² + 5x + 2 = 0 Quadratic

x + 4 = 0 Not Quadratic

A quadratic equation must only have the highest exponent of 2.

The highest exponent of quadratic equation is 2

while

Not quadratic or should I say the linear equation has the exponent of 1
