Solution for (1/2*9.8*t^2)-(0.46*1/2*9.8*t^2)-(1/2*9.8*(t-1)^2) equation: 


t in (-oo:+oo)

9.8*(1/2)*t^2-(9.8*(1/2)*(t-1)^2)-(9.8*((0.46*1)/2)*t^2) = 0

9.8*(1/2)*t^2-4.9*(t-1)^2-2.254*t^2 = 0

4.9*t^2-4.9*(t-1)^2-2.254*t^2 = 0

4.9*t^2-4.9*(t-1)^2-2.254*t^2 = 0

9.8*t-2.254*t^2-4.9 = 0

9.8*t-2.254*t^2-4.9 = 0

9.8*t-2.254*t^2-4.9 = 0

DELTA = 9.8^2-(-4.9*(-2.254)*4)

DELTA = 9.8^2-44.1784

DELTA = 51.8616

DELTA > 0

t = ((9.8^2-44.1784)^(1/2)-9.8)/(-2.254*2) or t = (-(9.8^2-44.1784)^(1/2)-9.8)/(-2.254*2)

t = -0.22182786*((9.8^2-44.1784)^(1/2)-9.8) or t = 0.22182786*((9.8^2-44.1784)^(1/2)+9.8)

(t+0.22182786*((9.8^2-44.1784)^(1/2)-9.8))*(t-0.22182786*((9.8^2-44.1784)^(1/2)+9.8)) = 0

(t+0.22182786*((9.8^2-44.1784)^(1/2)-9.8))*(t-0.22182786*((9.8^2-44.1784)^(1/2)+9.8)) = 0

( t+0.22182786*((9.8^2-44.1784)^(1/2)-9.8) )

t+0.22182786*((9.8^2-44.1784)^(1/2)-9.8) = 0 // - 0.22182786*((9.8^2-44.1784)^(1/2)-9.8)

t = -(0.22182786*((9.8^2-44.1784)^(1/2)-9.8))

t = -0.22182786*((9.8^2-44.1784)^(1/2)-9.8)

( t-0.22182786*((9.8^2-44.1784)^(1/2)+9.8) )

t-0.22182786*((9.8^2-44.1784)^(1/2)+9.8) = 0 // + -0.22182786*((9.8^2-44.1784)^(1/2)+9.8)

t = -(-0.22182786*((9.8^2-44.1784)^(1/2)+9.8))

t = 0.22182786*((9.8^2-44.1784)^(1/2)+9.8)

t in { -0.22182786*((9.8^2-44.1784)^(1/2)-9.8), 0.22182786*((9.8^2-44.1784)^(1/2)+9.8) }
