Subtract y y from both sides of the equation. 4x−x2 −y = 0 4 x - x 2 - y = 0. Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 (a c) 2 a. Substitute the values a = −1 a = - 1, b = 4 b = 4, and c = −y c = - y into the quadratic formula and solve for x x. −4±√42 −4⋅(−1⋅(−y)) 2⋅−1 - 4 ± 4 2 - 4 ⋅ (- 1 ⋅ (- y)) 2 ⋅ - 1.

2017年6月12日 · y=x(4-x)=-x(x-4) 抛物线，开口向下，0点x=0，x=4，顶点x=2，y=4； 对称轴x=2

Divide -4, the coefficient of the x term, by 2 to get -2. Then add the square of -2 to both sides of the equation. This step makes the left hand side of the equation a perfect square. Factor x^ {2}-4x+4. In general, when x^ {2}+bx+c is a perfect square, it can always be factored as \left (x+\frac {b} {2}\right)^ {2}.
