On the integral multiplication and division of two mathematical problems. Very urgent!
1. Given that real numbers x and y satisfy x ^ 2-6xy + 9y ^ 2-2 (x-3y) + 1 = 0, what is x-3y equal to?
2. Given that the area of a rectangle is 4A ^ 2-2ab + 1 / 4B ^ 2, and the length of one side is 4a-b, what is the perimeter of the rectangle?
Very urgent! Just write the answer directly. If there is a process, it will be even better,
In 10 minutes,


1. X ^ 2-6xy + 9y ^ 2-2 (x-3y) + 1 = 0 (x-3y) ^ 2-2 (x-3y) + 1 = 0 (x-3y-1) ^ 2 = 0x-3y = 12.4a ^ 2-2ab + 1 / 4B ^ 2 = 1 / 4 (16a ^ 2-8ab + B ^ 2) = 1 / 4 (4a-b) ^ 2 because the area = length * width, the other side length = 1 / 4 (4a-b) ^ 2 / (4a-b) = 1 / 4 (4a-b) perimeter = 2 (length + width) = 2 [1 / 4 (4a-b) + (4a-b)]



Multiplication and division of integral
There is an integral on the left side of the balance. Please put an integral on the right side of the balance to keep the balance
The integral of the left side is [(2m-n) &# 178; - (2m + n) &# 178;] / 2Mn
a.4 b.-3 c.3 d.-4


[(4m²+n²-4mn)-(4m²+n²+4mn)]÷ 2mn
=[-8mn]÷2mn
=-4
Answer D

Xiao Hua and Xiao Ming work out an integral multiplication problem (2x + a) (3x + b) at the same time. Xiao Hua copies "a" in the first polynomial into - A, and the result is 6x2 + 11x-10; Xiao Ming copies "3x" in the second polynomial into x, and the result is 2x2-9x + 10. (1) do you know the values of a and B in the formula? (2) Please work out the correct result of this problem


(1) According to the meaning of the question, we can get: (2x-a) (3x + b) = 6x2 + (2b-3a) x-ab = 6x2 + 11x-10; (2x + a) (x + b) = 2x2 + (a + 2b) x + AB = 2x2-9x + 10, | 2B − 3A = 11A + 2B = − 9, the solution is: a = - 5, B = - 2; (2) the correct formula is (2x-5) (3x-2) = 6x2-19x + 10
