(Y-1) ^ 2 + 2Y (1-y) = 0 factorization,

(Y-1) ^ 2 + 2Y (1-y) = 0 factorization,

(y-1)^2+2y(1-y)=0
(y-1)^2-2y(y-1)=0
(y-1)[(y-1)-2y]=0
(y-1)(-1-y)=0
(y-1)(y+1)=0
Y = 1 or y = - 1

Factorization: (y bisection + 2Y) bisection + 2 (y bisection + 2Y) + 1

(y^2+2y)^2+2(y^2+2y)+1
=(y^2+2y+1)^2
=(y+1)^4

Factorization (x-1) x (x + 1) (x + 2) - 24
One additional question:
If a & # 178; + B & # 178; - a-8b + 16 & # 188; = 0, then a = B=

Original formula = [(x-1) (x + 2)] [x (x + 1)] - 24
=[(x²+x)-2](x²+x)-24
=(x²+x)²-2(x²+x)-24
=(x²+x-6)(x²+x+4)
=(x+3)(x-2)(x²+x+4)
