" 2."25x^(2)+50x+12=0

x^(2)-50x+25=0

Let cos alpha be a root of the equation 25x^(2) +5x -12 = 0 -1 lt x lt 0 ,then the value of sin^(2)alpha is

Let cos alpha be a root of the equation 25x^(2) +5x -12 = 0 -1 lt x lt 0 ,then the value of sin^(2)alpha is

If sinalphaandcosalpha are the roots of 25x^(2)+5x-12=0 then the value of sin2alpha is

cos alpha is a root of the equation 25x^(2)+5x-12=0,-1

(i) 12x^(2) + 11x + 2 = 0 (ii) 25y^(2) + 15y+2 = 0

If sin alpha and cos alpha are the roots of 25 x ^2 +5x-12=0 , then value of sin 2alpha is

I. x^(2) +20x + 4 = 50 -25x II. y^(2) - 10y - 24 = 0
