Help ! разложите трёхчлены на множители 1 49+14b+b^2 2 d^6+2a^2d^3+a^4 3 (9+14a^5)^2 4 16+120 k^5+225k^10 5 a^4-2a^2c^5+c^10 6 36a^2-12 b a +b^2 7 169c^6+286c^3+121 8 4m^2-52 n m+169 n^2 9 n^8+8k^3 n^4+16 k^6 10 d^10-16 b^3 d^5+64 b^6

1 49+14b+b^2 = (7+b)²
2 d^6+2a^2d^3+a^4 = (d³+a²)
3 (9+14a^5)^2  = (9+14a^5)*(9+14a^5)
4 16+120 k^5+225k^10 = (4+15k^5)²
5 a^4-2a^2c^5+c^10 = (a²-c^5)²
6 36a^2-12 b a +b^2 = (6a-b)²
7 169c^6+286c^3+121 = (13c³+11)²
8 4m^2-52 n m+169 n^2 = (2m-13n)²
9 n^8+8k^3 n^4+16 k^6 = (n^4+4k^3)²
10 d^10-16 b^3 d^5+64 b^6 = (d^5-8b³)²
