Question

solve by completing te square 5x^2=7x-4

Answer 1

When they say completing the square what comes to mind?

Answer 2

taking half of the coefficient and squaring it

Answer 3

coefficient of the x term

Answer 4

Actually, yes.

You want to get everything with an x to one side:

5x^2-7x=4

The bad part about completing the square is that the x^2 has to have a coefficient of 1 so now you "get" to divide it all by 5:

x^2-7x/5=4/5

Now add half the x's coeffiecent to both sides.
