Tolong dijawab dengan benar dan jelas buat tugas penting terimakasih
Jawaban:
nomor 3
a. p + 11 + 4p – 8
= p + 4p + 11 – 8
= 5p + 3
b. 2a + 4b – 5 + 3a – 7b – 8
= 2a + 3a + 4b – 7b – 5 – 8
= 5a – 3b – 13
c. 2x² – 3x + 27 + (-9x²) + 10x – 50
= 2x² + (-9x²) – 3x + 10x + 27 – 50
= -7x² + 7x – 23
nomor 4
a. 3b – 7 – 5b – 3
= 3b – 5b – 7 – 3
= -2b -10
b. 8c – 5 – 2c + 13
= 8c – 2c -5 + 13
= 6c + 8
c. 8k – b + 15 – (-12k) + 9b – 11
= 8k + 12k – b + 9b + 15 – 11
= 20k + 8b + 4
nomor 5
a. -3(a – 2b + 5)
= -3a – 6b – 15
b. 2p(p – 3q + 12)
= 2p² – 6pq + 24p
c. (x + 2)(x – 3)
= x² – 3x + 2x – 5
= x² – x – 5
d. 2(-8a – 3b) + 3(5a – 6b)
= -16a – 6b + 15a – 18b
= -16a + 15a – 6b – 18b
= -a – 24b
