Answer 1

$\large\sf{} {2x}^{2} - 4x = 0 \\ \large\sf{}2x \times \left(x - 2\right) = 0 \\ \large\sf{}2x \times\left(x - 2\right) \div 2 = 0 \div 2 \\ \large\sf{}x \times \left(x - 2\right) = 0 \div 2 \\ \large\sf{}x \times \left(x - 2\right) = 0 \\ \large\sf{}x = 0 \\ \large\sf{}x - 2 = 0 \\ \large\sf{}x - 2 + 2 = 0 + 2 \\ \large\sf{}x = 0 + 2 \\ \large\sf{}x = 2 \\ \\ \large\sf{} x_{1} = 0 \\\large\sf{} x_{2} = 2 \\ \\ \\ {\large\boxed{\boxed{  { \large \sf x_{1} = 0}}}} \\ {\large\boxed{\boxed{  { \large \sf x_{2} = 2 }}}}$
