Question

Alguem mim ajuda fazer essa conta√2x+10-2=2

Answer 1

$\sqrt{2} x + 10 - 2 = 2 \\ \sqrt{2} x + 8 = 2 \\ \sqrt{2x} = 2 - 8 \\ \sqrt{2x} = - 6 \\ x = \frac{ - 6}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ x = \frac{ - 6 \sqrt{2} }{2} \\ x = - 3 \sqrt{2}$

Answer 2

$\sqrt{2} x + 10 - 2 = 2 \\ \sqrt{2} x + 8 = 2 \\ \sqrt{2} x = 2 - 8 \\ \sqrt{2} x = - 6 \\ x = \frac{ - 6}{ \sqrt{2} } \\ x = \frac{ - 6}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ x = \frac{ - 6 \sqrt{2} }{ {( \sqrt{2} )}^{2} } \\ x = \frac{ - 6 \sqrt{2} }{2} \\ x = - 3 \sqrt{2}$
