Q. ить на множители многочлен\newline(1+4x2)y2+2(2xy)(1+2xy)+1 \left(1+4 x^{2}\right) y^{2}+2(2 x-y)(1+2 x y)+1
  1. Recognize pattern: Recognize the pattern in the given polynomial; it resembles the expansion of (a+b)2(a+b)^2, which is a2+2ab+b2a^2 + 2ab + b^2.
  2. Identify aa and bb: Identify aa and bb in the polynomial. Here, a=ya = y and b=(1+2xy)b = (1+2xy).
  3. Check with (a+b)2(a+b)^2: Write down the square of (a+b)(a+b) to check if it matches the given polynomial: (y+(1+2xy))2=y2+2y(1+2xy)+(1+2xy)2(y + (1+2xy))^2 = y^2 + 2y(1+2xy) + (1+2xy)^2.
  4. Expand (1+2xy)2(1+2xy)^2: Expand (1+2xy)2(1+2xy)^2 to see if it matches the given polynomial: (1+2xy)2=12+2(12xy)+(2xy)2=1+4xy+4x2y2(1+2xy)^2 = 1^2 + 2*(1*2xy) + (2xy)^2 = 1 + 4xy + 4x^2y^2.
  5. Match expanded forms: Now, check if the expanded form of (y+(1+2xy))2(y + (1+2xy))^2 matches the given polynomial: y2+2y(1+2xy)+(1+4x2)y2=y2+2y+4xy2+1+4x2y2y^2 + 2y(1+2xy) + (1+4x^2)y^2 = y^2 + 2y + 4xy^2 + 1 + 4x^2y^2.
