x^2 -7x-6=0

Answer 1

just plug and chug.

a=1
b=-7
c=-6

Answer 2

What do you mean?

Answer 3

first you need to know the quadratic equation

Answer 4

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

Answer 5

@derek4011 How did you get that?

Answer 6

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

Answer 7

So is that the answer?

Answer 8

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
