foci x^2+2x

Solution

foci

x^{2} + 2 x

Solution

(- 1, - \frac{3}{4})

Solution steps

Rewrite

y = x^{2} + 2 x

in the standard form

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

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

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

p

from the center

(- 1, - 1)

along the y-axis

(- 1, - 1 + p)

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

Refine

(- 1, - \frac{3}{4})

Popular Examples

foci x=+(y+1)^2-9 foci

x = + (y + 1)^{2} - 9

foci-3x^2+8x+896 foci

- 3 x^{2} + 8 x + 896

foci x^2+36 foci

x^{2} + 36

foci y=(40x^3)/(3x)foci

y = \frac{40 x ^{3}}{3 x}

foci x^2+10x-2y+21=0 foci

x^{2} + 10 x - 2 y + 21 = 0
