Presumably this is a quadratic equation question in the form of: 9x2-12x+4 = 0 When factored: (3x-2)(3x-2) = 0 Solution: x = 2/3 and also x = 2/3 (they both have equal roots)

What happens to the shape of an ellipse when the denominators are the same?
If you start with the following equation of an ellipse: x2/4 + y2/9 = c2 and transform the equation to 9x2/36 + 4y2/36 = 36c2 the denominators are the same but the equation is unchanged and so the ellipse remains exactly as it was before.
What is 9x - 4 equals 7x - 6?
This is a linear equation. The value x = -1 is the solution to this equation.
