Question

How do you solve `3x^2-15x=0`?

Answer 1

The solutions are
`color(blue)(x=0`
`color(blue)(x=5`

Explanation:

`3x^2 - 15x = 0`

`3x` is common to both terms of the L.H.S:

`3x( x - 5) = 0`

Equating each of the factors to zero we obtain the solutions:
`3x= 0 , x = 0/3, color(blue)(x=0`

`x- 5= 0 , color(blue)(x=5`
