$\textbf{HINT}$Add $$10$$ to both sides, then add $$2.25$$...

2. LevB4Lev

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.

5. ParthKohli

To both sides.

6. ParthKohli

$4x^2 - 3x + 2.25 = 12.25$Multiplying both sides by $$100$$ is an idea.

7. LevB4Lev

but where did you get 2.25 from?

8. ParthKohli

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

9. LevB4Lev

jeez i have no idea what that means
