x^2 + 2x + x + 2x + 30 = 180
Combine like terms ( 2x + x + 2x ) = 5x
x^2 + 5x + 30 = 180
Move the 30 to the other side of the equation( subtracting)
x^2 + 5x = 150
Move the one 150 to the other side of the equation( adding)
x^2 + 5x + 150 = 0
Now move the x^2 to the other side of the equation(adding)
5x + 150 = x^2
Ans that's the most I can simplify.
