please factor 4x2 - 4x - 3 = 0?

4x2 - 4x - 3 = 0

4x2 - 6x +2x - 3 = 0

2x(2x - 3) + (2x - 3) = 0

(2x + 1)(2x - 3) = 0

a general rule for ax^2 + bx + c

divide b in a factor such that their multiplication is ac

here in this problem b= -4

and ac = -12

b = -4 = -6 + 2

or you can simply use the formula

x= { - b +/-sqrt(b^2-4ac)}/2a

(X - x1)(X - x2) = 0

4x 2 X 3

That cannot be factored because 3-1=2 and 1-3=-2

4x² - 4x - 3 = 0

The traditional method of (4x )(x ) will not work because the middle term will be off no matter how we place the '1' and the '3' and the '+'s and '-'s.

So, the best we can do is to pull out 4x

4x(x - 1) - 3 = 0

Its (2x+1 )(2x-3).

Hi,

4x² - 4x - 3 =

(2x - 3)(2x + 1) <==ANSWER

I hope that helps!! :-)

4x2 - 4x - 3 = 0

(2x-3)(2x+1)=0

2x-3=0

2x=3

x= 3/2

2x+1=0

2x=-1

x= -1/2

(2x-3)(2x+1)=0

(2x-3) (2x+1)

my gulay...you should study your algebra well!

this is too easy, kid...there's no use asking this.

anyway, hope my answer's right.

(2x-3) (2x+1)

:)
