Factorise
4x^27x+3=
and
6x^2+10x5=
Thanks
Method would be goodas I am stuck.

1. (4x3)(x1)
2. Use the quadratic formula which you can find on youtube. 
Thanks,can you tell me the answer to the second one.

Ans also I got this far for the first part's method
4x^27x+3=
4x^23x4x+3=
x(4x3)1(4x+3)
but there is nothing similarhow did you get (4x3) for both of them. 
Can someone please helpI need to do this today.
All I need is the method and answer. 
4x^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).
