Question

How do you solve `4x^2- 4x - 3=0`?

Answer 1

Find factors of a and c that combine to give b, In this case
`(2x + 1)(2x - 3) = 0`

Explanation:

`ax^2 +bx + c = 0`
Find factors of a and c that combine to give b, In this case
`a = 2*2`
`c = 1*(-3)`
`b = 2*1 + 2*(-3)`
`(2x + 1)(2x - 3) = 0`
