Question 840469
You have the values for a, b, and c, and you have these from a quadratic equation based on general form {{{ax^2+bx+c=0}}};
just use the values in the general solution.  Simplify and compute!  What is the result?


{{{x=(-2.2*10^(-2)+- sqrt((2.2*10^(-2))^2-4*1*(-1.2*10^(-4))))/(2)}}}

{{{x=(-2.2*10^(-2)+- sqrt((2.2*10^(-2))^2+4*1*(1.2*10^(-4))))/(2)}}}

{{{x=(-2.2*10^(-2)+- sqrt((2.2^2)*10^(-4)+4*(1.2*10^(-4))))/(2)}}}

{{{x=(-2.2*10^(-2)+- (10^(-2))sqrt((2.2^2)+4*(1.2)))/(2)}}}

{{{x=(-2.2*10^(-2)+- (10^(-2))sqrt(9.64))/(2)}}}

{{{x=(-2.2*10^(-2)+- (10^(-2))3.1048)/(2)}}}



{{{x=(-2.2*10^(-2)+- 3.1048*10^(-2))/2}}}


{{{x=(-2.2*10^(-2)+- 3.1048*10^(-2))/2}}}

{{{x=(-5.3*10^(-2))/2}}}  OR {{{x=(0.90*10^(-2))/2}}}

{{{x=-2.7*10^(-2)}}}  OR  {{{x=0.45*10^(-2)}}}

{{{highlight(x=-2.7*10^(-2))}}}   OR   {{{highlight(x=4.5*10^(-3))}}}
