What is the answer to 6x squared plus 7x plus 2?

Answer 1

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
