Question

Hola Chic@s nesecito que me ayuden en estos problemas, son "Productos notables" y ayudenme a identificarlos cada problema:
1. (5X²-6)²=
2.(x+4)²=
3.(2x+8) (x-8)=
4.(3x-1)³=
5. (3x+4)³=

Answer 1

1-
$(5x {}^{2} ) ^{2} - 2 \times 5x {}^{2} \times 6 + 6 {}^{2} \\ 25x {}^{4} - 60x ^{2} + 36$
2-
$x ^{2} + 2x \times 4 + 4 {}^{2} \\ x {}^{2} + 8x + 16$
3-
$2x {}^{2} - 16x + 8x - 64 \\ 2x {}^{2} - 8x - 64$
4-
$(3x) {}^{3} - 3 \times (3x) {}^{3} \times 1 + 3 \times 3x \times 1 {}^{2} - 1 {}^{3} \\ 27x {}^{3} - 3 \times 9x {}^{2} \times 1 + 3 \times 3x \times 1 - 1 \\ 27x {}^{3} - 27x {}^{2} + 9x - 1$
