Question

RESUELVE LOS PRODUCTOS NOTABLES

1. (a + 1) (a + 2)=
2. (y - 3 )(y - 1)=
3. (-2x - 7) (-2x + 11)=
4. $(x2 + y2) (x2 - y)$

Answer 1

Explicación paso a paso:

1. (a + 1) (a + 2)

a² + 2a + a + 2

a² +3a + 2

2. (y - 3 )(y - 1)

y² - y - 3y +3

y² - 4y + 3

3. (-2x - 7) (-2x + 11)

4x² - 22x - 14x - 77

4x² - 36x - 77

4. (x² + y²) (x² - y)

${x}^{4} - {x}^{2} y + {x}^{2} {y}^{2} - {y}^{3}$
