A later education question and answer inquired students to state what they admit is the most important element for a student to do to be able to get success. The one which response stood out from the rest was practice. Persons who commonly successful do not become successful by being born. They work hard and commitment their lives to succeeding. If you want to obtain your goals, keep this in mind! shown below some question and answer examples that you may possibly benefit from to enriches your knowledge and gain insight that will guide you to maintain your school studies.
Which are the solutions of x2 = –5x + 8?
By using Bhaskara’s formula, we will see that the two solutions are:
- x = 1.25
- x = -6.25
How to solve a quadratic equation?
Here we have the equation:
x^2 = -5x + 8.
This is a quadratic equation, remember that for the general quadratic equation:
a*x^2 + b*x + c = 0
The solutions are given by Bhaskara’s formula:
We can rewrite our equation as:
x^2 + 5*x – 8 = 0
Using the above formula we get the solutions:
Then the two solutions are:
- x = (-5 + 7.5)/2 = 1.25
- x = (-5 – 7.5)/2 = -6.25
