в) $= 5a *(b+2a)$

г) $= - c^6 * (c-1)*(8c+1)$

2. ----

3. a) $z(z+5)=0$

$z=0\\z+5=0$

$z=0\\z=-5$

$z_{1} = -5 , z_{2} = 0$

б)

$y^{2} - 7,1y = 0\\y^2- \frac{71}{10}y = 0\\10y^2 - 71y=0\\y(10y-71)=0\\y=0\\10y-71=0\\y=0\\y= \frac{71}{10} \\y_{1} = 0 , y_{2} = \frac{71}{10}$

4. a) $6 c^2x^3-4c^3x^2+2cx^2 \\2cx^2(3cx-2c^2+1)$

б) $y(a+c)-x(a+c)\\(a+c)(y-x)$
