Tentukan hasil perkalian berikut! 1) (3x + 4) (x - 2) 2) (2x - 3) (x + 1) 3) (m + 2) (m - 1) 4) (3p - 7) (p - 3) 5) (x + 3) (x - 2) 6) (5x - 2) (7x - 3)

1. ( 3x + 4) ( x - 2)
= 3x ( x - 2) + 4 ( x - 2)
= 3x^ - 6x + 4x - 8

2. ( 2x - 3) ( x + 1)
= 2x ( x + 1) - 3 ( x + 1)
= 2x^ + 2x - 3x - 3
= 2x^ + x - 3

3. ( m + 2) ( m - 1)
= m ( m - 1) + 2 ( m - 1)
= m^ - m + 2m - 2
= m^ + m - 2

1. (3x+4) (x-2) = 3x² - 6x + 4x - 8
                      =3x²-2x-8
2. (2x-3) (x+1) = 2x²+2x-3x-3= 2x²-x-3
3. (m+2)(m-1) = m²-m+2m-2= m²+m-2
4. (3p-7) (p-3)= 3p²-9p-7p+21 = 3p²-16p+21
5. (x+3) (x-2) = x²-2x+3x-6= x²+x-6
.6. (5x-2) (7x-3) = 35x²-15x-14x+6= 35x²-29x+6
