If both 2xay4 and 12b2x2ya-b are binomial with respect to X and y, and the coefficients are equal, try to find the values of a and B

If both 2xay4 and 12b2x2ya-b are binomial with respect to X and y, and the coefficients are equal, try to find the values of a and B

According to the meaning of the question: a + 4 = 62 + A-B = 612b2 = 2, the solution: a = 2B = - 2

If (a-2b) x ^ 2Y ^ A-1 is a quintic monomial about x.y, what is the condition that A.B satisfies
If the answer is correct, I will give you a good comment and answer it before 10 o'clock

2+a-1=5
a=4
A-2b is not equal to 0
B is not equal to a / 2
B is not equal to 2

If (A-1) x ^ 2Y ^ B is a quintic monomial about X, y, and the coefficient is - (1 / 2), then a = what, B = what

a-1=-1/2,a=1/2
2+b=5
b=3
