Question

x²+x²=3V2 me ajudem a encontrar a resposta por favor

Answer 1

x² + x² = 3√2
2x² = 3√2  
x² = 3.√2/ 2
x = +/- √(3.√2/ 2)

x1 = + √(3.√2/ 2)
x2 = - √(3.√2/ 2)

Answer 2

x² + x² = 3√2


$x^2 + x^2 = 3 \sqrt{2} \\ \\ \\ 2x^2 = 3 \sqrt{2} \\ \\ \\ x^2 = \dfrac{3 \sqrt{2} }{2} \\ \\ \\ x = \pm ~ \sqrt{\dfrac{3 \sqrt{2} }{2} } \\ \\ \\ x' = - \dfrac{ \sqrt{6 \sqrt{2}} }{2} \\ \\ \\ x'' = \dfrac{ \sqrt{6 \sqrt{2}} }{2}$
