-
A.
-3,2 -
B.
-2,3 -
C.
-2,9 -
D.
-9,2/3 -
E.
2/3, 9.
Correct Answer: Option D
Explanation
3x(^2) + 25x – 18 = 0
3x(^2) + 27x – 2x – 18 = 0
3x(x + 9) – 2(x + 9) = 0
(3x – 2)(x + 9) = 0
x = (frac{2}{3}) or x = -9.
Solve the equation 3x(^2) + 25x -18 = 0
3x(^2) + 25x – 18 = 0
3x(^2) + 27x – 2x – 18 = 0
3x(x + 9) – 2(x + 9) = 0
(3x – 2)(x + 9) = 0
x = (frac{2}{3}) or x = -9.
