The heartland of the Cholas was the fertile valley of the Kaveri River, but they ruled a significantly larger area at the height of their power from the later half of the 9th century till the beginning of the 13th century.
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ is
...I. 6 y² + 11 y – 7= 0
II. 21 x² + 5 x – 6 = 0
I. 2x2 + 12x + 18 = 0
II. 3y2 + 13y + 12 = 0
Equation 1: 2x2 - 21x + 54 = 0
Equation 2: 4y2 - 23y + 15 = 0
Difference between the roots of equation 1 is approx...
I. y² - 7 y – 18 = 0
II. x² + 10 x + 16 = 0
I. x² - 208 = 233
II. y² + 47 - 371 = 0
I. 104x² + 9x - 35 = 0
II. 72y² - 85y + 25 = 0
In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer
I. 7x² - 19x + 10 = 0...
I. 15b2+ 26b + 8 = 0
II. 20a2+ 7a - 6 = 0
I. x² + 3x – 154 = 0
II. y² + 5y – 126 = 0
