Step-by-step explanation:
Given the following Quadratic equation:
You can change its formed by Completing the square.
In order to do Complete the square, you can follow these steps:
1. You can identify that:
2. Then, you can find . This is:
3. Now you must add to both sides of the Quadratic equation in order to keep the balance. Then:
4. Finally, simplifying by actoring and adding the like terms, you get:
Answer:
x = 3
Step-by-step explanation:
calculate the slope using the slope formula and equate the result to - 2
m =
with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (x, 8)
m = =
= - 2, thus
- 2(x - 5) = 4, that is
- 2x + 10 = 4 ( subtract 10 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3
