" 9."2x^(2)+x-6=0

Use the remainder theorem to factorise the expression 2x^(3) + x^(2) + 7x-6 . Hence, solve the equation 2x^(3) + 9x^(2) + 7x-6=0

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

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

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

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 lenght of the common chord of circles x^(2)+y^(2)-6x-16=0 and x^(2)+y^(2)-8y-9=0 is

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

Equation of tangents drawn from (0, 0) to x^(2) + y^(2) - 6x -6y + 9 = 0 are
