Pertanyaan

Selesaikanlah Aljabar Berikut
1. (x+2) (x+1)
2.(a-3) (a+5)
3.(6+2) (b-7)
4.(p-6) (p-4)

Answer 1

1. x^2 + 3x + 2
2. a^2 + 2a - 15
3. b^2 - 5b - 14
4. p^2 - 10p + 24

Answer 2

1. (x+2)(x+1)=x²+x+2x+2=x²+3x+2
2.(a-3)(a+5)=a²+5a-3a-15=a²+2a-15.
3.(6+2)(b-7)=8(b-7)=8b-56
4.(p-6)(p-4)=p²-4p-6p+24=p²-10p+24
