Answer:
[tex] x = \dfrac{-4 \pm \sqrt{37}}{3} [/tex]
x = 0.69 or x = -3.36
Step-by-step explanation:
3j² + 8j − 7 = 0
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
a = 3
b = 8
c = -7
[tex] x = \dfrac{-8 \pm \sqrt{8^2 - 4(3)(-7)}}{2(3)} [/tex]
[tex] x = \dfrac{-8 \pm \sqrt{64 + 84}}{6} [/tex]
[tex] x = \dfrac{-8 \pm \sqrt{148}}{6} [/tex]
[tex] x = \dfrac{-8 \pm 2\sqrt{37}}{6} [/tex]
[tex] x = \dfrac{-4 \pm \sqrt{37}}{3} [/tex]
x = 0.69 or x = -3.36
