x^2=81/100.
We move all terms to the left:
x^2-(81/100.)=0
We add all the numbers together, and all the variables
x^2-(+81/100.)=0
We get rid of parentheses
x^2-81/100.=0
We multiply all the terms by the denominator
x^2*100.-81=0
Wy multiply elements
100x^2-81=0
a = 100; b = 0; c = -81;
Δ = b2-4ac
Δ = 02-4·100·(-81)
Δ = 32400
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{32400}=180$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-180}{2*100}=\frac{-180}{200} =-9/10 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+180}{2*100}=\frac{180}{200} =9/10 $
