What are the roots of the equation?
Arada [10]

Answer:

D

Step-by-step explanation:

Given

x² + 6x - 9 = 0 (add 9 to both sides )

x² + 6x = 9

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 9 + 9

(x + 3)² = 18 ( take the square root of both sides )

x + 3 = ± \sqrt{18} = ± \sqrt{9(2)} = ± 3\sqrt{2}

Subtract 3 from both sides

x = - 3 ± 3\sqrt{2} → D

What is -884/70 in simplest form?
cestrela7 [59]
-884/70
(-884/2)/(70/2) (divide top & bottom by two)
-442/35
*check - bottom can only be divided by 1, 5, and 7.
*1 won't change anything.
*top obviously cannot be divided by 5.
*check if top can be divided by 7.
     7*60 = 420
     442 - 420 = 22
     22 is not divisible by 7.
     Therefore, 442 is not divisible by 7.
*Therefore, -442/35 is simplest form.
