Question
Where was the Akash Prime air defence system recently
tested at high altitude by the Indian Army?Solution
The Akash Prime air defence system was tested successfully in eastern Ladakh, at an altitude of over 15,000 feet. The system achieved two direct hits on fast-moving aerial targets during high-altitude trials.
I. 63x² + 37 x – 40 = 0
II. 15 y² + 29 y + 12 = 0
I. 7p + 8q = 80
II. 9p – 5q = 57
I. 14p2 – 135p + 81 = 0
II. 7q2 – 65q + 18 = 0
Find the maximum value of f(x)= –2x² +8x + 3.
Solve the quadratic equation:
5x² − 13x + 6 = 0
For 3x² − 10x − 8 = 0, find (1/α + 1/β).
I.√(3x-17)+ x=15
II. Â y+ Â 135/y=24Â
Find the value of 'x' and 'y' in the following equation:
7x - 2y = 46
I. y² - 7 y – 18 = 0
II. x² + 10 x + 16 = 0
- If the quadratic equation x² + 18x + n = 0 has real and equal roots, what is the value of n?
