If using the method of completing the square to solve the quadratic equation x^2-13x+5=0, which number would have to be added to "complete the square"?

Answers

Answer 1

Answer:

(13/2)^2

Step-by-step explanation:

Hope this will help

Answer 2

Solving the quadratic equation by completing the square method (13/2)² is added.

What is a quadratic equation?

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

One method for locating the roots of a quadratic equation is to complete the square method. We must convert the given equation into a perfect square using this method. The quadratic formula can also be used to calculate the roots of a quadratic equation.

The given quadratic equation is x²-13x+5=0. Solve the equation by completing the square method as

x² - 13x + 5 = 0

( x - 13 / 2 )² = -5 + (13/2)²

Here in the equation (13/2)² is added to solve it by completing the square method.

Hey There!

To solve this problem we have to add the total number of students recorded.

10+8+9+6+2=35

then we divide 35 from 100 ( we do this when trying to find percentages

[tex]\frac{100}{35}=2.87142857[/tex]

then we multiply that by how many students that were able to do at least 30 or more push ups

we see that 8 students were able to do at least 30 or more push ups so we multiply

2.87142857x8= which is equal to 22.8

then we round to the nearest whole and get that

23% of the students were able to do 30 or more pushups

hope this helps :)
