Verified answer

(x-10)⁴-121=0
((x-10)²)²-11²=0
((x-10)²-11)*((x-10)²+11)=0
(x-10)²-11=0 или (x-10)²+11=0

1. (x-10)²-11=0. x²-20x+81=0. D=(-20)²-4*1*89=400-356=44
$x_{1} = \frac{-(-20)- \sqrt{44} }{2*1} = \frac{20-2 \sqrt{11} } {2} =10- \sqrt{11}$
$x_{2} =10+ \sqrt{11}$

2. (x-10)²+11=0. x²-20x+111=0. D=-44. корней нет

ответ: x₁=10-√11, x₂=10+√11
