7x+3x-(10x^2)=5+x
We move all terms to the left:
7x+3x-(10x^2)-(5+x)=0
determiningTheFunctionDomain -10x^2+7x+3x-(5+x)=0
We add all the numbers together, and all the variables
-10x^2+7x+3x-(x+5)=0
We add all the numbers together, and all the variables
-10x^2+10x-(x+5)=0
We get rid of parentheses
-10x^2+10x-x-5=0
We add all the numbers together, and all the variables
-10x^2+9x-5=0
a = -10; b = 9; c = -5;
Δ = b2-4ac
Δ = 92-4·(-10)·(-5)
Δ = -119
Delta is less than zero, so there is no solution for the equation
