Double roots of a quadratic equation shows that they are same root, and the graph of the quadratic function merely touches the input axis.
Let there is a quadratic function as:
The input axis is 'x-axis' and the output axis is 'y-axis'
When the output is 0, we get the graph of that function touching the x-axis since the place where y is 0 is only x-axis.
Thus, putting gives us the values of x for which the graph of the function
intersects the x-axis.
These points of interesection are called roots of the quadratic equation.
If the graph only touches the input axis (here x-axis), then both the roots are lying on same point and therefore are of equal measurement.
This is the condition when we call that the considered quadratic equation has double roots.
Let we consider and example of a quadraticfunction which will have double root.
Since (x-3)(x-3) = 0 will give x= 3 two times, that means the roots of the equation (x-3)(x-3) are same, and are equal to 3.
So, is one such quadraticfunction having double roots, as shown in the image attached below.

Answer:
Step-by-step explanation: When the left side factors into two linear equations with the same solution, the quadratic equation is said to have a repeated solution. We also call this solution a root of multiplicity 2, or a double root.
The answer is 9,000 or 9 thousand.
9 ten thousand are a unit form. The standard form is 90,000.
Explanations and an example of questions about the four types of number forms can be found at brainly.com/question/4725342.
The key problem is working out the value of 90,000 divide by 10. This is a division operation.
Option-1
Both numbers are divided by 10.
The result is
Option-2
Division operations can be written as fractions, like this.
The numerator and denominator are both divided by 10, or 'cross out a zero from both'.
The result is
- - - - - - -
If x is divided by y equals z, then x is equal to y multiplied by z.
Let's prove it!
This is proven.

Answer:
The standard form of nine ten thousand is 90,000.
Here, our task is to divide 90,000 by 10.
If we divide 90,000 by 10 then the answer is 9,000.
=90,000/10=9,000.
