k2=4/9
We move all terms to the left:
k2-(4/9)=0
We add all the numbers together, and all the variables
k2-(+4/9)=0
We add all the numbers together, and all the variables
k^2-(+4/9)=0
We get rid of parentheses
k^2-4/9=0
We multiply all the terms by the denominator
k^2*9-4=0
Wy multiply elements
9k^2-4=0
a = 9; b = 0; c = -4;
Δ = b2-4ac
Δ = 02-4·9·(-4)
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{144}=12$$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12}{2*9}=\frac{-12}{18} =-2/3 $$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12}{2*9}=\frac{12}{18} =2/3 $
