(-2/9)(x-4)=7/18
We move all terms to the left:
(-2/9)(x-4)-(7/18)=0
Domain of the equation: 9)(x-4)!=0We add all the numbers together, and all the variables
x∈R
(-2/9)(x-4)-(+7/18)=0
We get rid of parentheses
(-2/9)(x-4)-7/18=0
We multiply parentheses ..
(-2x^2-2/9*-4)-7/18=0
We calculate fractions
((-2x^2-2*18)/()+()/()=0
We calculate terms in parentheses: +((-2x^2-2*18)/()+()/(), so:We get rid of parentheses
(-2x^2-2*18)/()+()/(
We add all the numbers together, and all the variables
(-2x^2-2*18)/()+1
We multiply all the terms by the denominator
(-2x^2-2*18)+1*()
We add all the numbers together, and all the variables
(-2x^2-2*18)
We get rid of parentheses
-2x^2-2*18
We add all the numbers together, and all the variables
-2x^2-36
Back to the equation:
+(-2x^2-36)
-2x^2-36=0
a = -2; b = 0; c = -36;
Δ = b2-4ac
Δ = 02-4·(-2)·(-36)
Δ = -288
Delta is less than zero, so there is no solution for the equation
