y=2(1/2)+9
We move all terms to the left:
y-(2(1/2)+9)=0
We add all the numbers together, and all the variables
y-(2(+1/2)+9)=0
We multiply all the terms by the denominator
y*2)+9)-(2(+1=0
Wy multiply elements
2y^2+1=0
a = 2; b = 0; c = +1;
Δ = b2-4ac
Δ = 02-4·2·1
Δ = -8
Delta is less than zero, so there is no solution for the equation
