y^2= 1/4

Lösung

y^{2} = \frac{1}{4}

y = \frac{1}{2}, y = - \frac{1}{2}

Dezimale

y = 0.5, y = - 0.5

Schritte zur Lösung

y^{2} = \frac{1}{4}

Für

x^{2} = f (a)

sind die Lösungen

x = f (a), - f (a)

y = \frac{1}{4}, y = - \frac{1}{4}

\frac{1}{4} = \frac{1}{2}

- \frac{1}{4} = - \frac{1}{2}

y = \frac{1}{2}, y = - \frac{1}{2}

3 w^{2} + 15 w = 0

0 = \frac{50 + \frac{x ^{2}}{2} + 6 x}{2}

co m pl e t es q u a re x^{2} - 7 x + 6 = 0

x^{2} - 20 x + 9 = 0

so l v e f or B, x^{2} - 5 x + A = (x + B)^{2}
