Float x 2 y x+3/2
WebDec 29, 2024 · The x-vertex of a quadratic equation y = ax2 + bx +c is given by − b 2a. Plugging in a = 1, b = 6, and c = 5, we find that the x-vertex is − 6 2 = − 3. Now we plug in x = − 3 into y = x2 + 6x +5 to get the y-vertex, which is −4. So our vertex is ( −3, −4). Web阅读下面解题过程,然后解答问题: 解方程:x 4-x 2-6=0 设y=x 2 ,则原方程可化为y 2-y-6=0,解得:y 1 =3,y 2 =-2 当y=3时, x 2 =3,?∴x=±
