6x^2-7x-55=7
We move all terms to the left:
6x^2-7x-55-(7)=0
We add all the numbers together, and all the variables
6x^2-7x-62=0
a = 6; b = -7; c = -62;
Δ = b2-4ac
Δ = -72-4·6·(-62)
Δ = 1537
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-7)-\sqrt{1537}}{2*6}=\frac{7-\sqrt{1537}}{12} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7)+\sqrt{1537}}{2*6}=\frac{7+\sqrt{1537}}{12} $
