Answer: [tex]x=19/20[/tex] [tex]or[/tex] [tex]x=29/20[/tex]

Simplify both sides of the equation

[tex]400x^2-960x+593=42[/tex]

Subtract 42 from both sides

[tex]400x^2-960x+593-42=42-42\\400x^2-960x+551=0[/tex]

Factor left side of equation

[tex](20x-19)(20x-29)=0[/tex]

Set factors equal to 0

[tex]20x-19=0[/tex]   [tex]or[/tex]     [tex]20x-29=0[/tex]

[tex]x=19/20[/tex]    [tex]or[/tex]     [tex]x=29/20[/tex]
