and

6x^2+10x-5=

Thanks

Method would be good-as I am stuck.

**George**, Tuesday, November 2, 2010 at 3:19pmAns also I got this far for the first part's method

4x^2-7x+3=

4x^2-3x-4x+3=

x(4x-3)-1(4x+3)

but there is nothing similar-how did you get (4x-3) for both of them.

**Henry**, Thursday, November 4, 2010 at 9:31pm4x^2 - 7x + 3.

Use the AC Method:

A * C = 4 * 3 = 12 = -3 * -4,

4X^2 + (-3X + -4X) +3,

Group the 4 terms into 2 factorable pairs:

4x^2 -4x) + (-3x + 3),

Factor 4x from the 1st pair & -3 from

the 2nd pair:

4x(x - 1) + -3(x - 1),

Factor (x - 1) from each term:

(x - 1) (4x - 3).
