Perkalian Dua Faktor Aljabar.

Jawaban soal a.
(a + b)x + (a + b)y
= (x + y)(a + b)

Jawaban soal b.
(c - a)y - (c - a)²
= (c - a) [(c - a) - y]
= (c - a)(a - c + y)

Jawaban soal c.
a² + ab - ac - bc
= (a² - ac) + (ab - bc)
= a(a - c) + b(a - c)
= (a + b)(a - c)

Jawaban soal d.
a³ - 3a + 2a² - 6
= (a³ + 2a²) + (-3a - 6)
= a²(a + 2) - 3(a + 2)
= (a + 2)(a² - 3)

Jawaban soal e.
6x² + 3x - 8x²y - 4xy
= x²(6 - 8y) + x(3 - 4y)
= 2x²(3 - 4y) + x(3 - 4y)
= (2x² + x)(3 - 4y)
