Question 174282
{{{35x^2+9x-2}}}

we have several choices for the squared part of the factor
:
1 and 35
5 and 7

for the constant we  have 1 and 2:
:
between those combinations we have to get the middle term of 9x. If we dont find a combination we can use the quadratic formula
:
{{{(5x+2)(7x-1)}}}
:
5x+2=0--->5x=-2--->x=-2/5
7x-1=0---->7x=1--->x=1/7
:
x={{{system(-2/5,1/7)}}}
