Question 24
Quadratic EquationsSolve the equation 2a2 − 3a − 27 = 0.
- A.3/2, 9
- B.−2/3, 9
- C.3, 9/2
- D.−3, −9/2
- E.−3, 9/2
Show the answer and explanation
Answer: E (−3, 9/2)
Explanation
2a2 − 3a − 27 = (2a − 9)(a + 3) = 0, so a = 9/2 or a = −3.
Solve the equation 2a2 − 3a − 27 = 0.
Answer: E (−3, 9/2)
2a2 − 3a − 27 = (2a − 9)(a + 3) = 0, so a = 9/2 or a = −3.
