Answer:

[tex]$x=\frac{-9\pm\sqrt{161}}{4}$[/tex]

Step-by-step explanation:

[tex]2x^2+9x-10=0[/tex]

Using the quadratic formula:

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

[tex]$x=\frac{-9\pm\sqrt{9^2-4(2)(-10)}}{2(2)}$[/tex]

[tex]$x=\frac{-9\pm\sqrt{81-(-80)}}{2(2)}$[/tex]

[tex]$x=\frac{-9\pm\sqrt{81+80}}{2(2)}$[/tex]

[tex]$x=\frac{-9\pm\sqrt{161}}{4}$[/tex]
