IBPS · 2021
Solve both equations and form a new equation in variable 'z' (reduce to lowest possible factor) using roots of equation 1 and 2 as per instructions given below.
2 - 11/x + 9/x² = 0
(y - 2)² = 2 ¼
What will be new equation if roots of this are highest root of equation 1 and lowest root of equation 2.
- A.
8z² - 34z - 9 = 0
- B.
