foci x^2-15x

Solution

foci

x^{2} - 15 x

Solution

(\frac{15}{2}, - 56)

Solution steps

Rewrite

y = x^{2} - 15 x

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{225}{4})) = (x - \frac{15}{2})^{2}

(h, k) = (\frac{15}{2}, - \frac{225}{4}), p = \frac{1}{4}

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(\frac{15}{2}, - \frac{225}{4})

along the y-axis

(\frac{15}{2}, - \frac{225}{4} + p)

= (\frac{15}{2}, - \frac{225}{4} + \frac{1}{4})

Refine

(\frac{15}{2}, - 56)

Popular Examples

foci 2(x+1)^2 foci

2 (x + 1)^{2}

foci (x+3)^2=-12(y-5)foci

(x + 3)^{2} = - 12 (y - 5)

foci-2x^2+20x-52 foci

- 2 x^{2} + 20 x - 52

foci x^2+6x+9 foci

x^{2} + 6 x + 9

foci+x^2+8x-80 foci

+ x^{2} + 8 x - 80
