## TheYankee one year ago Can somebody show me how to factor this quadratic equation?

1. TheYankee

2x^2 – 5x – 3

2. Er.Mohd.AMIR

2x2-(6-1)x-3=2x2-6x+x-3

3. anonymous

$x=(-b \pm \sqrt{b ^{2}-4ac})\div2a$

4. Er.Mohd.AMIR

2*3=6 make factor of 6 as difference is middle term that is 5

5. TheYankee

Oh! Quadratic formula. Yes. Would the solved product be the factored form?

6. TheYankee

I'm going to be putting it into a rational expression :)

7. anonymous

I'm fairly sure, yes.

8. TheYankee

I'll post what I got in a minute. Could ya'll check it over?

9. anonymous

Sure :)

10. TheYankee

I got 3 or -0.5. Correct? And also, if that's factored, how do I know which to choose...?

11. anonymous

Okay I don't know if I messed up or not but I got 5.83? I'm probably very wrong. xD I'm sorry.

12. TheYankee

That's alright :/ I'll have to try elsewhere. Thanks anyway! I just double checked my answers, here, though http://www.math.com/students/calculators/source/quadratic.htm
