(0.6+x)(0.6+x)/(1.4-x)=0

Solution for (0.6+x)(0.6+x)/(1.4-x)=0 equation:

(0.6+x)(0.6+x)/(1.4-x)=0


Domain of the equation: (1.4-x)!=0

We move all terms containing x to the left, all other terms to the right

-x!=-1.4

x!=-1.4/-1

x!=1+0.4/1

x∈R


We add all the numbers together, and all the variables

(x+0.6)(x+0.6)/(-1x+1.4)=0

We multiply parentheses ..

(+x^2+0.6x+0.6x+0.36)/(-1x+1.4)=0

We multiply all the terms by the denominator


(+x^2+0.6x+0.6x+0.36)=0

We get rid of parentheses

x^2+0.6x+0.6x+0.36=0

We add all the numbers together, and all the variables

x^2+1.2x+0.36=0

a = 1; b = 1.2; c = +0.36;
Δ = b2-4ac
Δ = 1.22-4·1·0.36
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
