Question

Solutia negativa a ecuatiei x la puterea a doua= 49 supra 36

Answer 1

$x^2= \frac{49}{36} \\\\ \sqrt{x^2}= \sqrt{\frac{49}{36}} \\\\ |x|= \frac{7}{6} \\\\ x = \pm \frac{7}{6} \\\\ \hbox{Solutia negativa a ecuatiei este:} \ \boxed{x \to - \frac{7}{6}}$

Answer 2

x^2=49/36 x^2=7/6 x=+,-sqrt(7/6)=+,-sqrt7/sqrt6;solutia negativa este -sqrt7/sqrt6
