Assuming you mean x squared plus 5x squared... the answer is 6x squared.

-x2+2x
if its x(squared) its 7x(cubed) if its 2xX its 14x(squared)
X2 (X squared)
Your expression is this... x2 + y2/x
x2 + 8x2 = 9x2
(12x2 + 18) / (3x2 + 6) = (4x2 + 6) / (x2 + 2)
x2 + x2 = 2x2 2x^2
Assuming you mean x squared plus 5x squared... the answer is 6x squared.
x^3 - 121x
x3+3x2+3x+2 divided by x+2 equals x2+x+1
2x2 + x2 = 3x2

(x2 + 14 + 48 / (x + 8) = (x2 + 62) / (x + 8) =(x2 + 8x - 8x - 64 + 126) / (x + 8) = x - 1 + 126/(x+8)
-x2+2x
x2 + 9x2 = 10x2
