Question

como resolver :(x+5)(x-3)(2x-1)=0

Answer 1

Explicação passo-a-passo:

$\sf (x+5)\cdot(x-3)\cdot(2x-1)=0$

• $\sf x+5=0~\longrightarrow~x'=-5$

• $\sf x-3=0~\longrightarrow~x"=3$

• $\sf 2x-1=0~\longrightarrow~2x=1~\longrightarrow~x'''=\dfrac{1}{2}$

$\sf S=\left\{-5,\dfrac{1}{2},3\right\}$
