Question

1.(y+2)(y-4)
2.(t-1)(t+1)
3.(n-3)(n-5)
4.(2x+3)(x-2)
5.(4c-3)(3c+5)

Answer 1

1. y²-4y+2y-8 = y²-2y-8
2. t²+t-t-1 = t²-1
3. n²-5n-3n+15 = n²-8n+15
4. 2x²-4x+3x-6 = 2x²-x-6
5. 12c²+20c-9c-15 = 12c²+11c-15

Answer 2

1. y2 - 4y + 2y - 8
y2 - 2y - 8
2. t2 + t - t - 1
t2 - 1
3. n2 - 5n - 3n + 15
n2 - 8n + 15
4. 2x2 - 4x + 3x - 6
2x2 - x - 6
5. 12c2 + 20c - 9c - 15
12c2 + 11c - 15
maaf kalo salah, semoga bermanfaat !!
