In my textbook it says that some quadratic equations can have infinite solutions. For example if x 2 − 2 x = x 2 − 3 then rather than cancelling x 2 from both sides the book lets x = 1 m and then rearranges to get 1 − 2 m = 1 − 3 m 2 or m ( 3 m − 2) = 0 therefore m = 0 or m = 2 3 giving x = ∞ or 3 2. This is the first time I see ... WebAs you can see in the graph pictured above, the parabola touches the x axis in two different places. This means the quadratic equation x 2 – 6x + 8 has two real roots, x = 2 and x = 4 (that is, both of the x values where the parabola and x axis intersect).. Be careful: for a quadratic equation to have two real roots, its graph must touch the x axis twice. signs of glutathione deficiency
