10=(9900/(x^2))+21

Solution for 10=(9900/(x^2))+21 equation:

10=(9900/(x^2))+21

We move all terms to the left:

10-((9900/(x^2))+21)=0


Domain of the equation: x^2)+21)!=0

x!=0/1

x!=0

x∈R


We multiply all the terms by the denominator


-((9900+10*x^2)+21)=0


We calculate terms in parentheses: -((9900+10*x^2)+21), so:

(9900+10*x^2)+21

We get rid of parentheses

10*x^2+9900+21

We add all the numbers together, and all the variables

10x^2+9921

Back to the equation:

-(10x^2+9921)


We get rid of parentheses

-10x^2-9921=0

a = -10; b = 0; c = -9921;
Δ = b2-4ac
Δ = 02-4·(-10)·(-9921)
Δ = -396840
Delta is less than zero, so there is no solution for the equation
