If you want to find the roots of 0 = x^2+5x - 6, identify the coefficients of the x terms as follows: a=1, b=5 and c= -6.
-5 plus or minus sqrt( 25-4(1)(-6) )
Then x = -------------------------------------------------
2
-5 plus or minus sqrt(49)
= ------------------------------------
2
Thus, there will be two unequal, real answers. Please finish the math and identify these answers.
