Plis ayudenmeee!! Ayuda!!

Answer 1

Explicación paso a paso:

1) (a + 1) ( a + 2) =

${a}^{2} + 3a + 2$

2) ( x + 2) ( x + 4) =

${x}^{2} + 6x + 8$

3) ( x + 5) ( x - 2) =

${x}^{2} + 3x - 10$

4) ( m - 6) (m - 5) =

${m}^{2} - 11m + 30$

5) ( x + 7) (x - 3) =

${x}^{2} + 4x - 21$

6) ( x + 2) ( x - 1) =

${x}^{2} + 3x + 2$

7) ( x - 3) (x - 1) =

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

8) ( x - 5) ( x + 4) =

${x}^{2} - x - 20$

9) (a2 + 4) (a2- 4) =

${a}^{4} - 16$

10) (ab + 3) (3 - ab) =

$63 - 7 {a}^{2} {b}^{2}$
