Answer:
[tex]4x^2-5x+8=0[/tex]
Step-by-step explanation:
[tex]4x^2-3x+9=2x+1[/tex]
We need to get the equation in standard form:
[tex]ax^2+bx+c=0[/tex]
Subtract [tex]2x[/tex] from both sides of the equation:
[tex]4x^2-5x+9=1[/tex]
Subtract [tex]1[/tex] from both sides of the equation:
[tex]4x^2-5x+8=0[/tex]
