X*X+6X=87
We move all terms to the left:
X*X+6X-(87)=0
We add all the numbers together, and all the variables
6X+X*X-87=0
Wy multiply elements
X^2+6X-87=0
a = 1; b = 6; c = -87;
Δ = b2-4ac
Δ = 62-4·1·(-87)
Δ = 384
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}$$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{384}=\sqrt{64*6}=\sqrt{64}*\sqrt{6}=8\sqrt{6}$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-8\sqrt{6}}{2*1}=\frac{-6-8\sqrt{6}}{2} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+8\sqrt{6}}{2*1}=\frac{-6+8\sqrt{6}}{2} $
