24=4.9x^2+10x+40
We move all terms to the left:
24-(4.9x^2+10x+40)=0
We get rid of parentheses
-4.9x^2-10x-40+24=0
We add all the numbers together, and all the variables
-4.9x^2-10x-16=0
a = -4.9; b = -10; c = -16;
Δ = b2-4ac
Δ = -102-4·(-4.9)·(-16)
Δ = -213.6
Delta is less than zero, so there is no solution for the equation
