Answer :
Answer:
[tex]x=\frac{-5+-i\sqrt{23} }{4}[/tex]
Step-by-step explanation
The quadratic formula is [tex]x=-\frac{-b+-\sqrt{bx^{2 -4ac} } }{2a}[/tex]
Answer:
-5 ± sqrt(73))
----------------------------
4
Step-by-step explanation:
2x^2 +5x =6
Subtract 6 from each side
2x^2 +5x -6 =0
This is in the form
ax^2 +bx+c where a=2 b=5 and c=-6
The quadratic is -b ± sqrt(b^2 -4ac)
----------------------------
2a
-5 ± sqrt(5^2 -4(2)(-6))
----------------------------
2(2)
-5 ±sqrt(25 +48))
----------------------------
4
-5 ± sqrt(73))
