- x²+2√3x _ 9 = 0
- (4-k)x^2 + (2k+4)x + (8k+1) = 0
- factorise 7x^2-9x+2
- For what value of k , (4-k)x2 +(2k+4)x +(8k+1) = 0 is a perfect square
- Find the value of k for which the roots of this equation are real and equal k^2 x^2 - 2(2k-1)x + 4= 0
- for what value of 'k' will the following quadratic equation: (k+1)x2-4kx+9=0 have real and equal roots? Solve the equation.
