1)








2)

$= > \bf \: 3z - 5 {z }^{2} = 0 \\ \\ or. \: \: - z(5z - 3) = 0 \\ \\ or. \: \: \: 5z - 3 = 0 \\ \\ or. \: \: \bf \: z = \frac{3}{5} ....(answer)$

3)

$= > \bf \: 3 {x}^{2} - 5x - 2 = 0 \\ \\ or. \: \: 3 {x}^{2} - 6x + x - 2 = 0 \\ \\or. \: \: 3x(x - 2) + 1(x - 2) = 0 \\ \\ or. \: \: (3x + 1)(x - 2) = 0 \\ \\ or. \: \: \bf \: x = - \frac{1}{3} ....or...x = 2$
