Answer 1

x = (7 ± √13 )/6  if 3x² - 7x  + 3  = 0

Step-by-step explanation:

3x² - 7x  + 3  = 0

for ax² + bx  + c = 0

D = b² - 4ac

x =  (- b ± √D )/2a

Comparing 3x² - 7x  + 3  with  ax² + bx  + c

a = 3

b = - 7

c = 3

D = b² - 4ac  = (-7)² - 4(3)(3)

=> D = 49 - 36

=> D = 13

x =  (- b ± √D )/2a

=> x =  (-(-7) ± √13 ) / (2 * 3)

=> x = (7 ± √13 )/6
