Answer:

No solutions

Step-by-step explanation:

2x^2 + 5x + 4 = 0 ---> a = 2, b = 5, c = 4

[tex]x = \frac{-b +- \sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]x = \frac{-5 +- \sqrt{5^{2} - 4(2)(4)}} {2(2)}[/tex]

[tex]x = \frac{-5 +- \sqrt{25 - 32} }{4}[/tex]

[tex]x = \frac{-5+-\sqrt{-7}}{4}[/tex]

Since the number inside the square root is negative, the answer will be no solutions.

Hope this helps!
