4.) x = 0
5.) x = 0
13/33
We look for a number that can divide into 13 and 33 at the same time in order to reduce it.
There is none. So it remains the same as its simplest form.
= 13/33

Answer:
{x = -1 + √13 , x = -1 - √13}
Step-by-step explanation:
<u><em>Completing the square</em></u>:
f(x) = x² + 2x - 12
= x² + 2x + 1 - 1 - 12
= (x² + 2x + 1) - 1 - 12
= (x + 1)² - 13
<u><em>Solving</em></u>:
f(x) = 0
⇔ (x + 1)² - 13 = 0
⇔ (x + 1)² = 13
⇔ x + 1 = √13 or x + 1 = -√13
⇔ x = -1 + √13 or x = -1 - √13
2.4 +2/5 = 2.8
2.8 / 1/5= 70 / 5 = 14 / 1
