h=(7/10)(220-20)
We move all terms to the left:
h-((7/10)(220-20))=0
We add all the numbers together, and all the variables
h-((+7/10)200)=0
We multiply all the terms by the denominator
h*10)200)-((+7=0
Wy multiply elements
10h^2+7=0
a = 10; b = 0; c = +7;
Δ = b2-4ac
Δ = 02-4·10·7
Δ = -280
Delta is less than zero, so there is no solution for the equation
