The focal point F of the parabola is on the positive half axis a (M. - 3) of the x-axis, and the standard equation is solved on the parabola AF5

The focal point F of the parabola is on the positive half axis a (M. - 3) of the x-axis, and the standard equation is solved on the parabola AF5

Let Y & # 178; = 4PX, then the focus (P, 0), a is on the parabola, AF = 5, then 4pm = 9, (M-P) &# 178; + 9 = 25, then
(M + P) ² = (M-P) ² + 4pm = 25, then | m + P | = 5, | M-P | = 4, because the focus f is on the positive half axis of x-axis, we know that M > 0, P > 0,
So m and P are 9 / 2 and 1 / 2 respectively, and the standard equation y & # 178; = 2x or Y & # 178; = 18x
