Question

rezolvați in r ecuatiile x²-15x=0​

Answer 1

Explicație pas cu pas:

$\bf {x}^{2} - 15x = 0$

$\bf x \cdot(x - 15) = 0$

$\bf \red{ \underline{x_{1} = 0}}$

$\bf x - 15 = 0\implies \: \red{ \underline{x_{2} = 15}}$

Answer 2

$\it x^2-15x=0 \Rightarrow x(x-15)=0 \Rightarrow \begin{cases}\ \it x_1=0\\ \\ \it x-15=0 \Rightarrow x_2=15\end{cases} \Rightarrow S=\{0,\ \-15\}$
