In order to find the answer to the question u need to get x by its self
Square
Rectangle
because right angles means 90 degrees and the others have acute angles and obtuse angles in them.
Since we know that all angles in a triangle add up to 
, we can solve for 
and substitute it back into 
to find 
.
Remove the parentheses and combine like terms.
Add 
to both sides of the equation.
Divide both sides of the equation by .
Now that we have the value of , we can substitute it back into to find .
(f-g)(x) = f(x) - g(x)
= (x^3 -2x+6) - (2x^3+3x^2-4x+2)
= x^3 -2x +6 -2x^3 -3x^2 +4x -2 . . . . distribute the negative sign
= (1-2)x^3 -3x^2 +(-2+4)x +(6-2) . . . . . combine like terms
(f-g)(x) = -x^3 -3x^2 +2x +4
