Question

find the roots of the quadratic equations x²/9 -4=0​

Answer 1

Answer:

» x²/9 - 4 = 0

» x² = 36

» x = ± 6

Answer 2

Answer:

x = 6 or x = -6

Step-by-step explanation:

$\frac{x^{2} }{9} -4=0\\\\x^{2}-36=0\\\\x^{2}-6^{2} =0\\\\(x-6)(x+6)=0$

x - 6=0                  x+6=0

x = 6                      x = -6
