First here is the quadratic formula:
The standard form of a quadratic equation is
So we are going to use the quadratic formula to solve
a in our problem is 1
b in our problem is 7
c in our problem is 6
so first fill in these numbers for a, b, and c
at this point lets split the equations in to two seperate equations
we are doing this because of the +- in front of the square root
so now we have this:
AND
AND
AND
AND
So the solutions for x are -1 AND -6
check both in the original equation
----------------------
The both work so we can be sure we have solved the equation correctly.
