ayuda por favor no entiendo :(​

Answer 1

Respuesta:

Desarrolle las siguientes expresiones.

$a. \: (x+2)^{2}$

${x}^{2} + 2x \times 2 + {2}^{2}$

$\boxed{x^{2}+4x+4}$

$b. \: (y + 4 {)}^{2}$

${y}^{2} + 2y \times 4 + {4}^{2}$

$\boxed{{y}^{2}+8y+16}$

$c. \: (a + 5 {)}^{2}$

${a}^{2} + 2a \times 5 + {5}^{2}$

$\boxed{{a}^{2}+10a+25}$

$d. \: (x + 6 {)}^{2}$

${x}^{2} + 2x \times 6 + {6}^{2}$

$\boxed{{x}^{2}+12x+36}$

Desarrolle las siguientes expresiones.

$a. \: (x - 3 {)}^{2}$

${x}^{2} - 2x \times 3 + {3}^{2}$

$\boxed{{x}^{2}-6x+9}$

$b. \: (y - 4 {)}^{2}$

${y}^{2} - 2y \times 4 + {4}^{2}$

$\boxed{{y}^{2}-8y+16}$

$c. \: (a - 6 {)}^{2}$

${a}^{2} - 2a \times 6 + {6}^{2}$

$\boxed{{a}^{2}-12a+36}$

$d. \: (y - 1 {)}^{2}$

${y}^{2} - 2y \times 1 + {1}^{2}$

$\boxed{{y}^{2}-2y+1}$
