erweitern ((0.675+2x)^2)/((0.5643-x)(0.7653-x))

Lösung

erweitern

\frac{( 0.675 + 2 x ) ^{2}}{( 0.5643 - x ) ( 0.7653 - x )}

\frac{0.455625 + 2.7 x + 4 x ^{2}}{0.43185879 - 1.3296 x + x ^{2}}

Schritte zur Lösung

\frac{( 0.675 + 2 x ) ^{2}}{( 0.5643 - x ) ( 0.7653 - x )}

(0.675 + 2 x)^{2} = 0.455625 + 2.7 x + 4 x^{2}

= \frac{0.455625 + 2.7 x + 4 x ^{2}}{( - x + 0.5643 ) ( - x + 0.7653 )}
