faktorisieren x^2-9x+20.25

Lösung

faktorisieren

x^{2} - 9 x + 20.25

(x - 4.5)^{2}

Schritte zur Lösung

x^{2} - 9 x + 20.25

Schreibe

x^{2} - 9 x + 20.25

um:

x^{2} - 2 x \cdot 4.5 + (20.25)^{2}

= x^{2} - 2 x \cdot 4.5 + (20.25)^{2}

Wende Formel für perfekte quadratische Gleichungen an:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

a = x, b = 4.5

= (x - 4.5)^{2}

f a c t or (x + 9)^{3} - y^{3}

f a c t or [(5 x + 3) + 2 y] [(5 x + 3) - 2 y]

f a c t or cos^{2} (y) + 2 cos (y) + 1

f a c t or 12 x^{2} - 3 x 7 - 8 x y + 2 y^{7}

f a c t or (x + 2 y)^{3} - (2 x - y)^{3}
