Question

4x^2-3x-10=0
solve each equation by completing the square

Answer 1

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

Answer 2

2.25?
4x^2-3x=10

Answer 3

where would i add 2.25

Answer 4

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

Answer 5

To both sides.

Answer 6

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

Answer 7

but where did you get 2.25 from?

Answer 8

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

Answer 9

jeez i have no idea what that means
