Given, 3x2 - 4x = -2
Then, 9x2 - 12x = -6;
9x2 - 12x + 4 = -2 {completing the square} ;
3x - 2 = ±i√2 {sq rt of both sides} ; and
3x = 2 ± i√2.
Therefore,
x = ⅓(2 ± i√2).

State the discriminant of the quadratic 3x2-4x plus 4 equals 0?
The discriminant is -32.
3X2 plus 4X plus 1 equals?
3x2 + 4x + 1 = ?? This is a quadratic equation. The equation can be made to equal any number and this will determine the corresponding values of x. EXAMPLE : 3x2 + 4x + 1 = 96 (x = 5 or x = -19/3) Alternatively, if x is known then this will determine the result. EXAMPLE : If x = 2 then (3 x 4) + (4 x 2) + 1 = 12 + 8 + 1 = 21 In normal use, a quadratic equation is presented as equal to zero. In this example : 3x2 + 4x + 1 = 0
