factor out the 7 first

divide them with 14

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

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

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

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

remember that \[\sqrt{-1}=i\]

let me know if you hve question

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

it just takes practise.....

do this one til you get the answer

you already know how to use the quadraic formula right?

a little but not really

ok try that till u get the answer
