X2=1.7x+0.6

Solution for X2=1.7x+0.6 equation:

X2=1.7X+0.6

We move all terms to the left:

X2-(1.7X+0.6)=0

We add all the numbers together, and all the variables

X^2-(1.7X+0.6)=0

We get rid of parentheses

X^2-1.7X-0.6=0

a = 1; b = -1.7; c = -0.6;
Δ = b2-4ac
Δ = -1.72-4·1·(-0.6)
Δ = 5.29
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{-(-1.7)-\sqrt{5.29}}{2*1}=\frac{1.7-\sqrt{5.29}}{2}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1.7)+\sqrt{5.29}}{2*1}=\frac{1.7+\sqrt{5.29}}{2}
