Question

VA ROG EX 5!
DAU COROANA!!!!

Answer 1

$\frac{1}{9} x {}^{2} = 16$

$\frac{1}{9} x {}^{2} - 16 = 0$

(scoatem radical din fiecare factor)

${ \frac{1}{9}x } - 4 = 0$

$( \frac{1}{9}x + 4)( \frac{1}{9}x - 4) = 0$

$\frac{1}{9}x + 4 = 0$

$\frac{1}{9} x = - 4$

$x = - 4 \div \frac{1}{9} = - 4 \times 9 = - 36$

$\frac{1}{9}x - 4 = 0$

$\frac{1}{9}x = 4$

$x = 4 \div \frac{1}{9} = 4 \times 9 = 36$

$solutiile \: sunt \: = (36 \: si \: - 36)$
