Answer:
x = 3 ± i ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Step-by-step explanation:
Given
x² - 6x + 12 = 0 ( subtract 12 from both sides )
x² - 6x = - 12
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = - 12 + 9
(x - 3)² = - 3 ( take the square root of both sides )
x - 3 = ±
= ± i
( add 3 to both sides )
x = 3 ± i ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Answer:
13
Step-by-step explanation:
25d - 12 = ?
1 day = 25(1) - 12 = 13
12 + 13 = 25
We would factor this
what 2 numbers multiply to get -12 and add to get -4?
-6 and 2
(x-6)(x+2)
the side lengths are (x-6) and (x+2)
