How to solve the square of x = 10

How to solve the square of x = 10


∵x²=10
∴x=±√10
∴x1=√10,x2=-√10



Finding the solution of square of X + 1 / x = 101 / 10


10x²+10=101x
10x²-101x+10=0
(10x-1)(x-10)=0
x=1/10,x=10



Solving equation 100 / (square of 100-x) = 12.7 / (10-x)


100 / (square of 100-x) = 12.7 / (10-x)
100/{(10+X)(10-X)}=12.7/(10-X)
100/(10+X)=12.7
100=127+12.7X
X=-27/12.7
X≈2.126
