ejercicios de binomios con termino comun , muchas gracias

Answer 1

1. (a + 2)(a + 3) = a² + a (2 + 3)+(2)(3)= a² + 5a + 6
2. (x + 5)(x + 4) = (x)² – x (5 + 4) + (5)(4)= x² + 9x + 20
3. (t + 2)(t - 3) = t² + t (2 – 3) + (2)(-3)= t² - t - 6
4. (a + 5)(a - 9) = a² + a (5 – 9) + (5)(-9)= a² – 4a – 45
5. (x - 8)(x - 1) = (x)² + x(- 8 + -1) + (- 8)(- 1)= x² - 9x + 8
6. (a - 7)( a – 9) = (a)² + a (-7 + -9) + (-7)(-9)= a² - 16 a + 63
7. (x + 2)(x - 12) = (x)² + x(2 - 12) + (2)(-12)= x² – 10x - 24
8. (x + 3)(x + 8) = x² + x(3 + 8) + (3)(8)= x² + 11x + 24
9. (x – 4)(x - 6) = (x)² + x(- 4 + - 6) + (-4)(- 6)= x² - 10x + 24
10. (x + 6)(x - 2) = (x)² + x(6 – 2) + (6)(-2)= x² + 4x - 12
11. (x – 3)(x - 8) = (x)² + x(-3 + - 8) + (- 3) (- 8)= x² - 11x + 24
12. (x – 13)(x + 2) = (x)² + x (-13 + 2) + (-13)(2)= x² - 11x - 26
