Question
$$25x^2+30x = 0$$
Answer
$$ \begin{matrix}x_1 = 0 & x_2 = -\dfrac{ 6 }{ 5 } \\[1 em] \end{matrix} $$
Explanation
In order to solve $ \color{blue}{ 25x^{2}+30x = 0 } $, first we need to factor our $ x $.
$$ 25x^{2}+30x = x \left( 25x+30 \right) $$$ x = 0 $ is a root of multiplicity $ 1 $.
The second root can be found by solving equation $ 25x+30 = 0$.
