Question

x^2-4x=0


x^2-9x=0


4x^2-12x=0
por favor con operación​

Answer 1

Explicación paso a paso:

⋆ x² - 4x = 0

x(x - 4) = 0

x = 0 ; x = 4

⋆ x² - 9x = 0

x(x - 9) = 0

x = 0 ; x = 9

⋆ 4x² - 12x = 0

4x(x - 3) = 0

x = 0 ; x = 3

Answer 2

Explicación paso a paso:

x² – 4x = 0

x ( x – 4 ) = 0

x = 0 , x = 4

--------------------------------

x² – 9x = 0

x ( x – 9 ) = 0

x = 0 , x = 9

-------------------------------------

4x² – 12x = 0

4x ( x – 3 ) = 0

x = 0 , x = 3
