a x^{2} + b x + c

x^{2} + \frac{4 x}{9}

Schreibe

x^{2} + \frac{4 x}{9}

in dieser Form:

x^{2} + 2 a x + a^{2}

2 a = \frac{4}{9} : a = \frac{2}{9}

Addiere und subtrahiere

(\frac{2}{9})^{2}

x^{2} + \frac{4 x}{9} + (\frac{2}{9})^{2} - (\frac{2}{9})^{2}

x^{2} + 2 a x + a^{2} = (x + a)^{2}

x^{2} + \frac{4}{9} x + (\frac{2}{9})^{2} = (x + \frac{2}{9})^{2}

(x + \frac{2}{9})^{2} - (\frac{2}{9})^{2}
