0=x^2+20-10.716
We move all terms to the left:
0-(x^2+20-10.716)=0
We add all the numbers together, and all the variables
-(x^2+20-10.716)=0
We get rid of parentheses
-x^2-20+10.716=0
We add all the numbers together, and all the variables
-1x^2-9.284=0
a = -1; b = 0; c = -9.284;
Δ = b2-4ac
Δ = 02-4·(-1)·(-9.284)
Δ = -37.136
Delta is less than zero, so there is no solution for the equation
