Find the roots of the following quadratic equations i) 6sqrt5 x^(2) – 9x -3sqrt5 = 0 ii) x^(2) - x - 12 = 0 iii) 2x^(2) - 6x + 7 = 0 iv) 4x^(2) - 4x+17 = 3x^(2) -10x-17 v) x^(2) + 6x + 34 = 0 vi) 3x^(2) + 2x - 5 = 0

Find the roots of the following quadratic equations (if they exist) by the method of comleting the square: (1) 2x^(2)+x-4=0 " "(2) 6x^(2)+18x+10=0 (3) x^(2)+5x+7=0" "(4)x^(2)+3sqrt(3)x-12=0

If f(x)={:{((x^(2)-3x+2)/(x-3)", for " 0 le x lt 4),((x^(2)-1)/(x-2)", for " 4 le x le 6):} , then on [0, 6]

If x^(4) - 3x^(2) - 1 = 0 , then the value of (x^(6)-3x^(2)+(3)/(x^(2))-(1)/(x^(6))+1) is :

I. 6x^(2)+x-1=0 II. 8y^(2)+10y+3=0

Solve |((x+1),0,0)) , ((2x+1),(x-1),0)) , ((3x+1),(2x-1),(x-2))| =0
