- Find the roots of the quadratic equation: 2x² + 3x - 9 = 0?
Question 1:
Find the roots of the quadratic equation: 2x² + 3x - 9 = 0? A. 3, -3/2
B. 3/2, -3
Feedback 2x² + 6x - 3x - 9 = 0
2x(x + 3) - 3(x + 3) = 0
(x + 3)(2x - 3) = 0
=> x = -3 or x = 3/2.
2x(x + 3) - 3(x + 3) = 0
(x + 3)(2x - 3) = 0
=> x = -3 or x = 3/2.
C. -3/2, -3
D. 3/2, 3
