Two sheets of paper
First: length a, width A-B (larger)
Second: length B, width A-B (smaller)
The area of this rectangle is (a + b) (a-b). The original area of the first paper is a (a-b), and the area of the second paper is B (a-b). The sum of the areas of the two papers is the square of a minus the square of B. so (a + B) (a-b) = A2-B2



Square of factoring factor-2 (m-n) + 32


-Square of 2 (m-n) + 32
=-2 [square of (m-n) - 16]
=-2(m-n+4)(m-n-4)



How to factorize the square of (M + n) - the square of n


Square of (M + n) - square of n
=(m+n+n)(m+n-n)
=m(2m+n)



Decomposition factor: M2 (A-2) + m (2-A)=______ .


m2(a-2)+m(2-a),=m2(a-2)-m(a-2),=m(a-2)(m-1).



The second power of factorization factor (m-2n) - the square of 2 (2n-m) (M + n) + (M + n)


(m-2n)^2-2(2n-m)(m+n)+(m+n)^2
={(m-2n)-(m+n)}^2
=(-3n)^2
=9n^2



If 5m = 8N (n ≠ 0), then M: n = () is the best answer of the first answer,


8:5



If 0.5m = 2n, then n=_______ ;


Divide both sides of the equation by 2, then n = 0.25m



Factorization of m-12mn ^ 4
a^2-4ab+4b^2-1
m-12mn^4


a^2-4ab+4b^2-1
=(a-2b)^2-1
=(a-2b+1)(a-2b+1)
m-12mn^4
=m(1-12n^4)
=m(1+2√3n^2)(1-2√3n^2)



Factorization (3 ^ 4) ^ m △ 27 ^ m


Original formula = 3 * (3 ^ 3M) / (3 ^ 3M)
=3*1
=3

Square factorization of m-6mn + 8N
Calculation by factorization
(1) Given x + y = 1, xy = negative half, find the square value of the algebraic formula x (x + y) (X-Y) - x (x + y) (2) if A-B = - 3, ab = 4, find the third power of half a - a square, b square + the third power of half ab
