Question

${2}^{2} - 14x = 0$
qual é o cálculo?​

Answer 1

Resposta:

$2 {}^{2} - 14x = 0 \\ 4 - 14x = 0 \\ - 14x = - 4 \\ x = \frac{14 \div 2}{4 \div 2} \\ x = \frac{7}{2}$

Answer 2

$\large\displaystyle \mathsf{2^2-14x=0 }$

$\large\displaystyle \mathsf{4-14x=0 }$

$\large\displaystyle \mathsf{-14x=-4 }$

$\large\displaystyle\text{ \boxed{\boxed{\mathsf{ x=\dfrac{2}{7}}}} }$
