Question
If it is possible to form a meaningful English word by
using the 2nd, 4th, 5th, and 8th letter (from the left end) of the word ‘RECESSION’ then which of the following will be second letter of the word formed from the left end. If more than one such meaningful word is formed mark ‘Z’ as your answer. If no meaningful word is formed, mark ‘X’ as your answer?Solution
2nd, 4th, 5th, and 8th letter (from the left end) of the word ‘RECESSION’ = E, E, S, O.
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 24x + 143 = 0
Equation 2: y² - 20y + 96 = 0
l. 3x2 + 17x + 24 = 0
II. 2y2 + 15y + 27 = 0
I. x2 – 3(x + 5) = -11
II. y2 – 4(y + 2) = -2y
I. 8a2 – 22a+ 15 = 0
II. 12b2 - 47b + 40=0
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ is
...I. 2y2 + 11y + 15 = 0
II. 3x2 + 4x - 4= 0
I. 3p² + 13p + 14 = 0
II. 8q² + 26q + 21 = 0
- Suppose both the roots of q² + kq + 49 = 0 are real and equal, then determine the value of 'k'.
I. x2 – 18x + 81 = 0
II. y2 – 3y - 28 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 34x + 285 = 0
Equation 2: y² - 26y + 165 = 0
