Question

49x2 - 14x - 3

Answer 1

are you trying to find the roots?

Answer 2

yes, sorry I wasn't more clear

Answer 3

it's okay.
When dealing with quadratic equations (polynomials with the highest degree of the variable being 2)
One can use the quadratic formula to find roots:
if f(x)=ax^2+bx+c=0
then x=-b/2+root(b^2-4ac)/2
and x= -b/2-root(b^2-4ac)/2

Answer 4

so in this case
roots are -1/7 and 3/7

Answer 5

The expression factors into (7 x-3) (7 x+1)
