f(x)=6x2+7x+2
f(x)=(6x+1)(x+2)
x= -1/6 and x= -2
The above answer is not correct. (6x+1)(x+2) yields 6x2+13x+2, not the original equation.
The answer can be arrived at using the quadratic equation, where ax2+bx+c=0 and
x=[-b (+-) square root(b2-4ac)] / 2a
x=[-7(+-) square root (72-4(6)(2))] / 2(6)
x=[-7(+-)square root(49-48)]/12
x=[-7(+-)1]/12
x=-1/2 and -2/3
