2x*9x+23=23351
We move all terms to the left:
2x*9x+23-(23351)=0
We add all the numbers together, and all the variables
2x*9x-23328=0
Wy multiply elements
18x^2-23328=0
a = 18; b = 0; c = -23328;
Δ = b2-4ac
Δ = 02-4·18·(-23328)
Δ = 1679616
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{1679616}=1296$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-1296}{2*18}=\frac{-1296}{36} =-36 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+1296}{2*18}=\frac{1296}{36} =36 $
