erweitern x^2+(2k-1)x+(k^2+2)

Lösung

erweitern

x^{2} + (2 k - 1) x + (k^{2} + 2)

x^{2} + 2 k x - x + k^{2} + 2

Schritte zur Lösung

x^{2} + (2 k - 1) x + (k^{2} + 2)

Apply rule:

a + (b + c) = a + b + c

(2 k - 1) x + (k^{2} + 2) = (2 k - 1) x + k^{2} + 2

= x^{2} + (2 k - 1) x + k^{2} + 2

= x^{2} + x (2 k - 1) + k^{2} + 2

Schreibe

x (2 k - 1)

um:

2 k x - x

= x^{2} + 2 k x - x + k^{2} + 2
