If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ is
...l). 2p² + 12p + 18 = 0
ll). 3q² + 13q + 12 = 0
I. x= √(20+ √(20+ √(20+ √(20…………….∞)) ) )
II. y= √(5√(5√(5√(5……….∞)) ) )
...I. x2 - 9x - 52 = 0
II. y2 - 16y + 63 = 0
I. x3 = 1728
II. y2 – 15y + 56 = 0
I. 3 x² - 10
