Make sure you write all the terms on the left-hand side of the equation and simplify as much as possible before using the Quadratic Formula.
- 4, - 9
We will use the Quadratic Formula to solve the given quadratic equation.
ax^2+ bx+ c=0 ⇕ x=- b± sqrt(b^2-4 a c)/2 a
Let's start by rewriting the equation so all of the terms are on the left-hand side and then simplify as much as possible.
Now, we can identify the values of a, b, and c. x^2+13x+36=0 ⇕ 1x^2+ 13x+ 36=0 We see that a= 1, b= 13, and c= 36. Let's substitute these values into the Quadratic Formula.
Substitute values
The solutions for this equation are x= - 13 ± 52. Let's separate them into the positive and negative cases.
| x=- 13± 5/2 | |
|---|---|
| x_1=- 13 + 5/2 | x_2=- 13 - 5/2 |
| x_1=- 8/2 | x_2=- 18/2 |
| x_1=- 4 | x_2=- 9 |
Using the Quadratic Formula, we found that the solutions of the given equation are x_1=- 4 and x_2=- 9.
