Question

Find the roots of the quadratic equation 3xsquare - 5x + 2 = 0 using the
quadratic formula​

Answer 1

3x² - 5x + 2 = 0

a = 3

b = - 5

c = 2

delta = b² - 4ac

delta = (-5)² - 3.2.2

delta = 25 - 12 = 13

x = ( - b +- raiz de delta ) / 2a

x = ( - (-5) +- raiz de 13 ) / 2.3

x = ( 5 +- 3,60 ) / 6

x' = ( 5 - 3,60 ) / 6 = 1,4 / 6 = 0,2333...

x" = ( 5 + 3,60 ) / 6 = 8,60 / 6 = 1,4333...
