If the roots of the equation 2x² - 5x + b = 0 are in the ratio of 2:3, then find the value of b?
Question 1:
If the roots of the equation 2x² - 5x + b = 0 are in the ratio of 2:3, then find the value of b?
A.3
FeedbackLet the roots of the equation 2a and 3a respectively. 2a + 3a = 5a = -(- 5/2) = 5/2 => a = 1/2 Product of the roots: 6a² = b/2 => b = 12a2 a = 1/2, b = 3.
