X^2+X^2=18+4X
We move all terms to the left:
X^2+X^2-(18+4X)=0
We add all the numbers together, and all the variables
X^2+X^2-(4X+18)=0
We add all the numbers together, and all the variables
2X^2-(4X+18)=0
We get rid of parentheses
2X^2-4X-18=0
a = 2; b = -4; c = -18;
Δ = b2-4ac
Δ = -42-4·2·(-18)
Δ = 160
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}$$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{160}=\sqrt{16*10}=\sqrt{16}*\sqrt{10}=4\sqrt{10}$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-4)-4\sqrt{10}}{2*2}=\frac{4-4\sqrt{10}}{4} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4)+4\sqrt{10}}{2*2}=\frac{4+4\sqrt{10}}{4} $
