(X-9)(X-9)=324
We move all terms to the left:
(X-9)(X-9)-(324)=0
We multiply parentheses ..
(+X^2-9X-9X+81)-324=0
We get rid of parentheses
X^2-9X-9X+81-324=0
We add all the numbers together, and all the variables
X^2-18X-243=0
a = 1; b = -18; c = -243;
Δ = b2-4ac
Δ = -182-4·1·(-243)
Δ = 1296
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}$$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{1296}=36$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-18)-36}{2*1}=\frac{-18}{2} =-9 $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+36}{2*1}=\frac{54}{2} =27 $
