Answer:
x = -3 or x = -6
Step-by-step explanation:
Solve for x over the real numbers:
3 x^2 + 27 x + 54 = 0
The left hand side factors into a product with three terms:
3 (x + 3) (x + 6) = 0
Divide both sides by 3:
(x + 3) (x + 6) = 0
Split into two equations:
x + 3 = 0 or x + 6 = 0
Subtract 3 from both sides:
x = -3 or x + 6 = 0
Subtract 6 from both sides:
Answer: x = -3 or x = -6
Answer:
x = -3, -6.
Step-by-step explanation:
3x2 + 27x + 54 = 0
Divide through by 3:
x^2 + 9x + 18 = 0
(x + 3)(x + 6) = 0
x = -3, -6.

x = 12
I would say B because of KAO keep add opposite.
28 of the missing number I would assume that because all the right side number are going up by 3 while all the left side are by 4 so 24+4=28
X equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two
