Question

Tolong dijawab ya,pakai cara,tentang al jabar!

Answer 1

5.-5p^2 - 10p - 4p^2 - 3p
= -5p^2 - 4p^2 - 10p - 3p
= -9p^2 -13p

6.6a^2 + 10a - 12a - 20
= 6a^2 + 8a - 20

7.4a^2 - 10ab - 6ab - 15b^2
= 4a^2 - 4ab - 15b^2

8.3x^3 - 9 x^2 - 2x^2 + 6x - 6x + 4
= 3x^3 - 7x^2 + 4

9. -(4p^2 + 12p + 9)
= -4p^2 - 12p - 9

itu saja ....semoga membantu
