Use the quadratic formula to solve the equation. x^2 -7x-6=0

OpenStudy (anonymous):

just plug and chug. a=1 b=-7 c=-6

OpenStudy (anonymous):

What do you mean?

OpenStudy (anonymous):

first you need to know the quadratic equation

OpenStudy (anonymous):

\[\frac{ -b \pm \sqrt{b ^{2}-4ac} }{ 2a }\]

@derek4011 How did you get that?

OpenStudy (anonymous):

its is general formula used in algebra to determine the two points in a quadractic where a value of X will give a value of Y=0

OpenStudy (anonymous):

So is that the answer?

OpenStudy (anonymous):

no, use the a, b, and c values tha @dhouser gave you andplug them into their respective values in the quadratic formula and solve in order to get your two values of X that produce Y=0
