Question

по алгебре помогите пожалуйста​

Answer 1

Ответ:

${x}^{3} - 7 {x}^{2} - 18x = x(x - 2)(x + 9) \\ \\ {x}^{4} - 6 {x}^{3} + 8 {x}^{2} = {x}^{2} (x - 2)(x - 4) \\ \\ - 12 {x}^{4} + 7 {x}^{3} - {x}^{2} = - {x}^{2} (4x - 1)(3x - 1) \\ \\ 9 {x}^{4} - 30 {x}^{3} + 25 {x}^{2} = {x}^{2} {(3x - 5)}^{2}$
