I can't figure out how to find the two solutions? how can you factor this?

2. pratu043 Group Title

3. anfar Group Title

use the formula ax^2+bx+c $x=(-b \pm \sqrt{b ^{2}-4ac})/2a$

4. whatevs Group Title

oh ok

5. whatevs Group Title

b= -9??

6. partyrainbow276 Group Title

wait i got it

For example, for the quadratic equation x2 + x - 12 = 0, x = 3 and x = -4 are both roots ... 9x2 = 81 (a = 9, b = 0, c = -81 since we could subtract 81 from both sides) ...

x=6.21

10. pratu043 Group Title

yes b = -9

Quadratic Equations AlgebraIn this case, the equation x2 - x - 2 = 0 can be broken apart into two factors [i.e., ... 9x2 = 81 (a = 9, b = 0, c = -81 since we could subtract 81 from both sides) ...

12. anfar Group Title

yes a=1, b=-9,c=4

13. whatevs Group Title

I got 9 +- sqrt 65 / 2

14. anfar Group Title

yes (9+- sqrt65)/2
