Answer:

x = - [tex]\frac{2}{3}[/tex] ± [tex]\frac{\sqrt{19} }{3}[/tex]

Step-by-step explanation:

given a quadratic equation in the form ax² + bx + c = 0

We can solve using the quadratic formula

with a = - 3, b= - 4 and c = 5

x = ( 4 ± [tex]\sqrt{(-4)^2-(4(-3)(5)}[/tex]) / - 6

  = ( 4 ± [tex]\sqrt{16+60}[/tex]) / - 6

  = ( 4 ± [tex]\sqrt{76}[/tex]) / - 6

  = (4 ± 2[tex]\sqrt{19}[/tex]) / - 6

  = - [tex]\frac{2}{3}[/tex] ± [tex]\frac{\sqrt{19} }{3}[/tex]
