Question

How do you solve `11x^2 - 9x = 0`?

Answer 1

You factor it.

Explanation:

Example: `5x^2-10x=0`

factoring x would give you
`x(5x-10)`

We know that x=0 which is outside the parenthesis

the second value is x = 2 from `10/5`
which is inside the parenthesis. It's a positive value since we do the reciprocal (opposite) the sign of the given.
