(a-10)(a+10)=200a=
We move all terms to the left:
(a-10)(a+10)-(200a)=0
We add all the numbers together, and all the variables
-200a+(a-10)(a+10)=0
We use the square of the difference formula
a^2-200a-100=0
a = 1; b = -200; c = -100;
Δ = b2-4ac
Δ = -2002-4·1·(-100)
Δ = 40400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{40400}=\sqrt{400*101}=\sqrt{400}*\sqrt{101}=20\sqrt{101}$$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-200)-20\sqrt{101}}{2*1}=\frac{200-20\sqrt{101}}{2} $$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-200)+20\sqrt{101}}{2*1}=\frac{200+20\sqrt{101}}{2} $
