erweitern (x-5)(x-6i)

Lösung

erweitern

(x - 5) (x - 6 i)

(x^{2} - 5 x) + (- 6 x + 30) i

Schritte zur Lösung

(x - 5) (x - 6 i)

Apply FOIL method

(x - 5) (x - 6 i) : x^{2} - 6 x i - 5 x + 30 i

= x^{2} - 6 x i - 5 x + 30 i

Rewrite in standard complex form:

(x^{2} - 5 x) + (- 6 x + 30) i

= (x^{2} - 5 x) + (- 6 x + 30) i

\frac{d}{d r ( x )} ((x) (\frac{r ( x ) ^{2}}{4} - r (x) s + s^{2}))

e x p an d \frac{x ( - 2 ln ( x y ) + 1 )}{y ^{3}}

e x p an d \frac{2 ( n + 1 ) ( 2 n + 1 )}{n ^{2}}

e x p an d (3 x + 2 y = 9.5) (x + y)

e x p an d 2 (x (x - 1))
