Simplify 2x+4y−2x
WebbIn mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For … WebbYou can give a rational parametrization using stereographical projection, as follows: The point ( 0, 0) is on the curve. Since the equation is quadratic, for each slope t, the line y = t x must intersect the curve at a second point. If you plug y = t x into the equation (and you assume x ≠ 0 ), then you should get that the coordinates of the ...
