x^2+3x+k(x)=0

Lösung

x^{2} + 3 x + k (x) = 0

(h, k) = (- \frac{3}{2}, \frac{9}{4}), p = - \frac{1}{4}

Schritte zur Lösung

x^{2} + 3 x + y = 0

Rewrite

x^{2} + 3 x + y = 0

in the standard form

4 (- \frac{1}{4}) (y - \frac{9}{4}) = (x - (- \frac{3}{2}))^{2}

Therefore parabola properties are:

(h, k) = (- \frac{3}{2}, \frac{9}{4}), p = - \frac{1}{4}

x^{2} - 2 y + 4 = 0

x + (y - 1)^{2} = 0

x = (y - 3)^{2}

3 y = - x^{2} + 4 x

y > x^{2}
