## anonymous 4 years ago Solve. 14x2 + 42x + 70 = 0

1. anonymous

factor out the 7 first

2. anonymous

divide them with 14

3. anonymous

14x^2/14 + 42x/14 + 70/14 = 0/14

4. anonymous

x^2 + 3x + 5 = 0 then try solving for x

5. anonymous

use quadratic formula $x=[-b-+\sqrt{(b^2 -4ac)}/2a$, here you a=1,b=3,c=5 try them

6. anonymous

youl get an answer of x=-1.5+1.66i and x=-1.5-1.66i ans...

7. anonymous

remember that $\sqrt{-1}=i$

8. anonymous

let me know if you hve question

9. anonymous

im def. lost math is not my strongest subject. i just cant get it

10. anonymous

it just takes practise.....

11. anonymous

do this one til you get the answer

12. anonymous

13. anonymous

a little but not really

14. anonymous
