135.
4x³y – 13x²y² + 8xy³
= xy( 4x² – 13xy + 8y² )
136.
$\frac{5}{2}$$x^{4}$ + $\frac{3}{4}$$x^{3}$ – $\frac{1}{5}$$x^{2}$
= x²( $\frac{5}{2}$x² + $\frac{3}{4}$x – $\frac{1}{5}$ )
137.
7$x^{5}$y – $\frac{3}{4}$$x^{4}$y² + 0,5x³y³ – 3xy$^{5}$
= xy( 7$x^{4}$ – $\frac{3}{4}$$x^{3}$y + 0,5x²y² – 3y$^{4}$ )
138.
12x²y²z – 8xy²z² – 0,1y²z³
= yz( 12x²y – 8xyz – 0,1yz² )
