Without solving, examine the nature of the roots of the equations : (i) 5x^(2)-6x+7=0 (ii) x^(2)+6x+9=0 (iii) 2x^(2)+6x+3=0

The nature of the roots of the equations x^(2) - 6x + 9=0 is :

The real numbers that satisfy the equation x^(2) +6 |x| -9 =0 are-

If f (x) =x ^(2) -6x + 9, 0 le x le 4, then f(3) =

If f (x) =x ^(2) -6x + 9, 0 le x le 4, then f(3) =

Draw the graph of y = x^(2) - 6x + 9 and hence solve x^(2) - 6x + 9 = 0.

Draw the graph of y=x^2-4x+3 and use it to solve x^(2) -6x+9=0

Solve by the method of completing the square: (1) 9x^(2)-15x+6=0 (2) 5x^(2)-6x-2=0

Show that x=-3 is solution of x^(2)+6x+9=0

Solve the following equation , 3x^2 +6x -9 =0
