In order to combine terms, the variable(s) must be the same and the exponent(s) must be the same on the variables. Since you have an x2 term, x term, xy term and y term, none of the terms can be combined. So, the answer is: x2 + 4x + xy + 4y. The only thing you could do in this problem is to factor out a 4 from the 4x & 4y so another way to write this is: x2 + xy + 4(x + y).

If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y

How do you factorise xy plus 3x?
the answer is x(3+y)
Xy plus yx equals 545 what is the value of x and y?
xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc
Factor 2xy - 4x plus 8y - 16?
( 2xy - 4x ) + ( 8y - 16)2 ( xy - 2x ) + 2 ( 4y - 8 ) Answer
Factor xy plus 2x plus 4y plus 8?
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
What is xy minus 2x plus 4y minus 8?
(y-2) (x+4)
Factor 2xy plus 4x plus 8y plus 16?
2xy + 4x + 8y + 16 = 2[xy + 2x + 4y + 8] = 2[x(y + 2) + 4(y + 2)] = 2(y + 2)(x + 4)
Factor completely xy - 2x plus 4y -8?
xy-2x+4y-8 x(y-2)+4(y-2) (x+4)(y-2)
Factor xy - 2x plus 4y - 8?
(x + 4)(y - 2)
Factor xy-2x plus 4y-8?
(x + 4)(y - 2)
How do you factor xy-2x plus 4y-8?
(x + 4)(y - 2)
How do you solve 4x-y2 and 3x y5?
