Mark me as brainlist
If you move (+) from One side to another side then it will convert into (-) and vice versa
OR
If you move (×) from One side to another side then it will convert into (÷) and vice versa
LHS = RHS
-x^2+60x+2700 = 0
If you move 2700 to RHS then its sign change from (+) to (-)
then the resulting equation will be
-x^2 +60x = -2700
Now if you move 60x to RHS then its sign change from (+) to (-)
then the resulting equation will be
-x^2 = -60x - 2700
After this if you move -x^2 to RHS then its sign changes from (-) to (+)
At last the resulting equation will be
x^2 -60x-2700 =0
I hope now you would easily understand why sign changes
