Question 1122910

{{{x(3x-1)=14}}}...first multiply

{{{3x*x-1*x=14}}}

{{{3x^2-x=14}}}

{{{3x^2-x-14=0}}}...factor

{{{3x^2+6x-7x-14=0}}}

{{{(3x^2+6x)-(7x+14)=0}}}

{{{3x(x+2)-7(x+2)=0}}}

{{{(x + 2) (3x - 7) = 0}}}

solutions:

if {{{x + 2 = 0}}}->{{{x=-2}}}

if {{{3x - 7 = 0}}}->{{{3x=7}}}->{{{x=7/3}}}
