0=-4.9t^2+0t+2.4
We move all terms to the left:
0-(-4.9t^2+0t+2.4)=0
We add all the numbers together, and all the variables
-(-4.9t^2+0t+2.4)=0
We get rid of parentheses
4.9t^2-0t-2.4=0
We add all the numbers together, and all the variables
4.9t^2-1t-2.4=0
a = 4.9; b = -1; c = -2.4;
Δ = b2-4ac
Δ = -12-4·4.9·(-2.4)
Δ = 48.04
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-\sqrt{48.04}}{2*4.9}=\frac{1-\sqrt{48.04}}{9.8} $$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+\sqrt{48.04}}{2*4.9}=\frac{1+\sqrt{48.04}}{9.8} $
