Question

how do i factor 2x^2-5x+3?

Answer 1

are you familiar with ,factoring by grouping?

Answer 2

yes but there are only 3 numbers.....

Answer 3

well, look at the middle number,

can you seperate that into 2 numbers that would allow you to factor by grouping?

Answer 4

examples
-5x=-2x+-3x
-5x=-4x+-1x
-5x=-6x+ 1x
-5x= 6x + -1x

Answer 5

(2x )(x ) and it has to be 3 and 1 if it's an easy factorization

Answer 6

thanks also how do you factor 2x^2+7x-15

Answer 7

You can use this formula: \[x _{1,2} = \frac{ -b \pm \sqrt{b ^{2} - 4ac} }{ 2a }\]
where a = 2, b = -5, c =3

Answer 8

The value of a,b and c, you can get from the equation \[ax ^{2}+bx+c\] You can solve the various forms of equations with ease.

Answer 9

This is just another of same (2x )(x ) and your 15 breaks out into 5 and 3

Answer 10

ya but they dont add to 7 right?......

Answer 11

depends on the sign and where you put each one....
