.77=1/2-9.8t^2
We move all terms to the left:
.77-(1/2-9.8t^2)=0
Domain of the equation: 2-9.8t^2)!=0We add all the numbers together, and all the variables
We move all terms containing t to the left, all other terms to the right
-9.8t^2)!=-2
t!=-2/1
t!=-2
t∈R
-(1/2-9.8t^2)+0.77=0
We get rid of parentheses
9.8t^2+0.77-1/2=0
We multiply all the terms by the denominator
(9.8t^2)*2-1+(0.77)*2=0
We add all the numbers together, and all the variables
(9.8t^2)*2+0.54=0
We multiply parentheses
18t+0.54=0
We move all terms containing t to the left, all other terms to the right
18t=-0.54
t=-0.54/18
t=-0.54/18
