0.7x(1-x)=0.8
We move all terms to the left:
0.7x(1-x)-(0.8)=0
We add all the numbers together, and all the variables
0.7x(-1x+1)-(0.8)=0
We add all the numbers together, and all the variables
0.7x(-1x+1)-0.8=0
We multiply parentheses
0x^2+0x-0.8=0
We add all the numbers together, and all the variables
x^2+x-0.8=0
a = 1; b = 1; c = -0.8;
Δ = b2-4ac
Δ = 12-4·1·(-0.8)
Δ = 4.2
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-\sqrt{4.2}}{2*1}=\frac{-1-\sqrt{4.2}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{4.2}}{2*1}=\frac{-1+\sqrt{4.2}}{2} $
