factor (4x)/(x-1)*(x^2-1)/(3x+3)

factor

\frac{4 x}{x - 1} \cdot \frac{x ^{2} - 1}{3 x + 3}

\frac{4 x}{3}

Solution steps

\frac{4 x}{x - 1} \cdot \frac{x ^{2} - 1}{3 x + 3}

\frac{x ^{2} - 1}{3 x + 3} = \frac{x - 1}{3}

= \frac{4 x}{x - 1} \cdot \frac{x - 1}{3}

Multiply fractions:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{4 x ( x - 1 )}{( x - 1 ) \cdot 3}

Cancel the common factor:

x - 1

= \frac{4 x}{3}

x^{4} - 2 x^{2} y^{2} + y^{4}

x^{2} + 4 x + 4 = 16

\frac{53}{43} \cdot \frac{46 n ^{2}}{31}

4 x^{2} + 20 x + 16

x - \frac{3}{5} x = 50
