You can put this solution on YOUR website! solve for x providing exact answers using radicals
as needed for the following equation x^2+12x+1=36
-------------------
x^2 + 12x - 35 = 0
---
a = 1 ; b = 12 ; c = -35
----
x = [-12 +- sqrt(144 -4*-35)]/2
---
x = [-12 +- sqrt(284)]/2
---
x = [-12 +- 2sqrt(71)]/2
---
x = [-6 +- sqrt(71)]

You can put this solution on YOUR website! x^2+12x+1=36
x^2+12x+1-36=0
x^2+12x-35=0
find the roots of the equation using formula
a=1b=12c=-35
x = [-12 +- sqrt(144 -4*-35)]/2
..
x = [-12 +- sqrt(284)]/2
..
x = [-12 +- 2sqrt(71)]/2
..
x = [-6 +- sqrt(71)]
