Solve: x² − 7x + 12 = 0
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.
I. x
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 5x + 6 = 0
Equation 2: y² - 7y + 12 = 0
l). 2p² - 10p - 48 = 0
ll). q ² + 5q - 234 = 0
I. 6x² - 49x + 99 = 0
II. 5y² + 17y + 14 = 0
I. 14p² + 9p - 8 = 0
II. 4q² - 19q + 12 = 0
I. 2x2 - 9 x + 9 = 0
II. 2y2 - 7 y + 3 = 0
I. 2x2 – 10x – 48 = 0
II. y2 – 16y – 297 = 0
I. 2y2 – 19y + 35 = 0
II. 4x2 – 16x + 15 = 0
If the roots of the quadratic equation 7y² + 5y + 9 = 0 are α and β, then find the value of [(1/α) + (1/β)].
