X^2+y=1,150

Solution for X^2+y=1,150 equation:

X^2+X=1.150

We move all terms to the left:

X^2+X-(1.150)=0

We add all the numbers together, and all the variables

X^2+X-(1.15)=0

We add all the numbers together, and all the variables

X^2+X-1.15=0

a = 1; b = 1; c = -1.15;
Δ = b2-4ac
Δ = 12-4·1·(-1.15)
Δ = 5.6
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{5.6}}{2*1}=\frac{-1-\sqrt{5.6}}{2}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{5.6}}{2*1}=\frac{-1+\sqrt{5.6}}{2}
