Answer:
Terms: –6xy² , – 4yx² , 8x², 2xy² , 7y, – 11x² , – 100x, – 11yx, 20x²y, – 6x² , y, 2xy
The terms and there variables:
-6xy² ⇒ xy²
-4yx² ⇒ yx² = x²y
8x² ⇒ x²
2xy² ⇒ xy²
7y ⇒ y
11x² ⇒ x²
-100x ⇒ x
-11yx ⇒ yx = xy
20x²y ⇒ x²y
-6x² ⇒ x²
y ⇒ y
2xy ⇒ xy
So the like terms are :
(-11xy , 2xy)
(-4yx², 20x²y)
(8x² , 11x² , -6x²)
(7y , y)
(2xy² , -6xy²)
(-100x) { Has no like terms}
