10=(9.8*t^2)/2

Solution for 10=(9.8*t^2)/2 equation:

10=(9.8t^2)/2

We move all terms to the left:

10-((9.8t^2)/2)=0

We multiply all the terms by the denominator


-((9.8t^2)+10*2)=0


We calculate terms in parentheses: -((9.8t^2)+10*2), so:

(9.8t^2)+10*2

We add all the numbers together, and all the variables

(9.8t^2)+20

We get rid of parentheses

9.8t^2+20

Back to the equation:

-(9.8t^2+20)


We get rid of parentheses

-9.8t^2-20=0

a = -9.8; b = 0; c = -20;
Δ = b2-4ac
Δ = 02-4·(-9.8)·(-20)
Δ = -784
Delta is less than zero, so there is no solution for the equation
