Answer 1

Answer:

I've equated to zero because it is a cubic polynomial. So, 3 solutions are possible which are +5, -5 and 0.

x³ -25x = 0

x³=25x

x²=25

x=±5

Answer 2

${x}^{3} - 25x \\ \\ x( {x}^{2} - 25) \\ \\ x( {x}^{2} - 5 {}^{2} ) \\ \\ x(x + 5)(x - 5) \: \: (by \: {x}^{2} - y {}^{2} = (x - y)( x + y)$
