    \[\textbf{HINT}\]Add \(10\) to both sides, then add \(2.25\)...

    2.25? 4x^2-3x=10

    This can be solved the same way I showed you before. Follow the example from your last complete the square problem.

    \[4x^2 - 3x + 2.25 = 12.25\]Multiplying both sides by \(100\) is an idea.

    but where did you get 2.25 from?

    When you are completing the square, you basically add \(\left(\dfrac{\text{coefficient of }x}{2}\right)^2\) to both sides.
