Answer:

[tex]x=\frac{5(+/-)\sqrt{41}} {4}[/tex]

Step-by-step explanation:

The formula to solve a quadratic equation of the form

[tex]ax^{2} +bx+c=0[/tex]

is equal to

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

in this problem we have

[tex]2x^{2} -5x+1=3[/tex]  

equate to zero

[tex]2x^{2} -5x+1-3=0[/tex]  

[tex]2x^{2} -5x-2=0[/tex]  

so

[tex]a=2\\b=-5\\c=-2[/tex]

substitute in the formula

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

[tex]x=\frac{5(+/-)\sqrt{41}} {4}[/tex]
