8-7/10h=6-1/3h
We move all terms to the left:
8-7/10h-(6-1/3h)=0
Domain of the equation: 10h!=0
h!=0/10
h!=0
h∈R
Domain of the equation: 3h)!=0We add all the numbers together, and all the variables
h!=0/1
h!=0
h∈R
-7/10h-(-1/3h+6)+8=0
We get rid of parentheses
-7/10h+1/3h-6+8=0
We calculate fractions
(-21h)/30h^2+10h/30h^2-6+8=0
We add all the numbers together, and all the variables
(-21h)/30h^2+10h/30h^2+2=0
We multiply all the terms by the denominator
(-21h)+10h+2*30h^2=0
We add all the numbers together, and all the variables
10h+(-21h)+2*30h^2=0
Wy multiply elements
60h^2+10h+(-21h)=0
We get rid of parentheses
60h^2+10h-21h=0
We add all the numbers together, and all the variables
60h^2-11h=0
a = 60; b = -11; c = 0;
Δ = b2-4ac
Δ = -112-4·60·0
Δ = 121
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{121}=11$$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-11)-11}{2*60}=\frac{0}{120} =0 $$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+11}{2*60}=\frac{22}{120} =11/60 $
