0=16t^2+48t+36=
We move all terms to the left:
0-(16t^2+48t+36)=0
We add all the numbers together, and all the variables
-(16t^2+48t+36)=0
We get rid of parentheses
-16t^2-48t-36=0
a = -16; b = -48; c = -36;
Δ = b2-4ac
Δ = -482-4·(-16)·(-36)
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$t=\frac{-b}{2a}=\frac{48}{-32}=-1+1/2$
