Please solve? x squared - 12x = -36
Since you need this to be in the format of ax^2 + bx + c in order to find x, add 36 to both sides, so that it becomes
x^2 -12x +36=0. ( a is 1, b is -12, and c is 36)
Then, you can apply it to the quadratic formula, which is -b±√(b^2-4ac)/2a
*Sorry, its a little unclear
I always like to do the b^2 - 4ac part first, because it saves me extra work if there’s no solutions (when the answer is negative) or just one solution (when the answer is 0)
In this case, there is only one solution, because (-12)^2 - 4 (1)(36) is 0.
So, since that’s 0, the answer would be -(-12)/2(1), which simplifies to ---->> 6!
