Question

X²- 15x = 0
Como posso resolver??

Answer 1

$\Large\mathsf\displaystyle{} {x}^{2} - 15x = 0 \\ \\ \Large\mathsf\displaystyle{}x\cdot\left(x - 15\right) = 0 \\ \Large\mathsf\displaystyle{}x = 0 \\ \Large\mathsf\displaystyle{}x - 15 = 0 \\\\ \Large\mathsf\displaystyle{}x = 0 \\ \Large\mathsf\displaystyle{}x = 15$

Solução:

$\Large\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ x_{1} = 0 }}}\end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ x_{2} = 15 }}}\end{gathered} }$

$\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{{ \red{Bons}} \blue{\:Estudos}}}}\end{gathered} }$
