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

Nov 12, 2015

You factor it.

Explanation:

Example: $5 {x}^{2} - 10 x = 0$

factoring x would give you
$x \left(5 x - 10\right)$

We know that x=0 which is outside the parenthesis

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