因式分解:(1) x^2+2x+1 (2) 1-6y+9y^2 (3) 1+m+m^2/4 (4) b^2-22b+121
因式分解:(1) x^2+2x+1 (2) 1-6y+9y^2 (3) 1+m+m^2/4 (4) b^2-22b+121

因式分解:(1) x^2+2x+1 (2) 1-6y+9y^2 (3) 1+m+m^2/4 (4) b^2-22b+121
(1) x^2+2x+1=(x+1)^2
(2) 1-6y+9y^2=(1-3y)^2
(3) 1+m+m^2/4 =(1+m/2)^2
(4) b^2-22b+121=(b-11)^2

(1)(x+1)² (2)(3y-1)² (3)((m/2)+1)²
(4)(b-11)²
