A factoring problem, ball process and answer 5X²z-20z-10px²+40p
First extract the common factor 5
=5(X²z-4z-2px²+8p)
Then group them
=5(X²z-2px²+8p-4z)
==5[X²(z-2p)+4(2p-z)]
=5(x^2-4)(z-2p)
=5(x+2)(x-2)(z-2p)
Factorization of 2 (a + b) ^ 2 - (a + b) - 1
2(a+b)^2-(a+b)-1
Cross multiplication
=(2a+2b+1)(a+b-1)
Factorization problem 2A ^ n-32a ^ n + 4
2a^n-32a^n+4
=-30a^n+4
=-2(15a^n-2)
Factorization of 16A ^ 2 - (2a-36) ^ 2
Original form
=(4a)²-(2a-36)²
=[4a-(2a-36)][4a+(2a-36)]
=(2a+36)(6a-36)
=12(a+18)(a-6)
Factorization (y + 2) x ^ 2 + (y + 2) x-12y-24
(y+2)x^2+(y+2)x-12y-24
=(y+2)(x^2+x-12)
=(y+2)(x+4)(x-3)
Factorization (y + 2) x & # 178; - 24 + (y + 2) x-12y
(y+2)x²—24+(y+2)x—12y
=(y+2)x²+(y+2)x—12(y+2)
=(y+2)(x²+x-12)
=(y+1)(x+4)(x-3)
Factorization; (1) (x + y) ^ 2 + 4 (x + y) + 4
(2)12a^3-12a^2+3ab^2 ; (3)(a+b)^2-4ab
(1)(x+y)^2+4(x+y)+4=(x+y+2)²(2)12a^3-12a^2b+3ab^2 =3a(4a²-4ab+b²)=3a(2a-b)²(3)(a+b)^2-4ab=a²+2ab+b²-4ab=a²-2ab+b²=(a-b)²
