Question

How to factor: 0 = 2x^2 - 5x + 2
This is what I have so far -
Factor by grouping:
Multiply the first coefficient 2, by the last coefficient 2
2 * 2 = 4

Find the product of 4, and the sum of the middle term -5
-1 * -4 = 4 and -1 + -4 = -5

Put the two new numbers in place of the middle term in the trinomial:
0 = 2x^2 - 4 - 5 + 2

Split the equation in half and group:
x^2 - 4 and -5 + 2

Now I am lost.
