Factorise

Question

4x^2-7x+3=

and

6x^2+10x-5=

Thanks

Method would be good-as I am stuck.

Answer 1

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

2. Use the quadratic formula which you can find on youtube.

Answer 2

Thanks,can you tell me the answer to the second one.

Answer 3

Ans 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.

Answer 4

Can someone please help-I need to do this today.

All I need is the method and answer.

Answer 5

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).
