## anonymous one year ago x^2 + 3x = 10 what do i do first do i subtract 2^x Or do i divide 3x/3 and 10/3?

1. pooja195

Are we supposed to factor this?

2. anonymous

No it doesn't say factor it says this Solve each quadratic equation. Show your work.

3. pooja195

Subtract 10 from both sides. $\huge~\rm~x^2+3x−10=10−10$ $\huge~\rm~x^2+3x−10=0$Factor left side of equation. $\huge~\rm~(x−2)(x+5)=0$

4. pooja195

From here solve for x x-2=0 x=? x+5=0 x=?

How did you get five if we subtract a 3 -10?

@pooja195

7. anonymous

Never mind i think i have it...

8. anonymous

@pooja195 is that all?

9. pooja195

I factored that part for u

10. anonymous

x= -7?

11. anonymous

-_-;

12. pooja195

You get 2 answers not one

13. anonymous

Okay

14. pooja195

Try again

15. pooja195

(x−2)(x+5)=0 x-2=0 to solve we add 2 to both sides because we are isolating x x=2 now try x+5=0

16. anonymous

x+5 0 -5 -5 = -5 x=-5?
