1. (x + k) (m + n) - 2. (6m + n)(11 − d) 3. (7c4 — ƒ2) (11ƒ – c3) 4. (a + 9x) (a2 + ax − x2) 5. (11n2m3 + 2n3m3) (5n3m2 – 3m2(

Answer

(x + k) (m + n) = xm + xn + km + kn
(6m + n)(11 − d) = 66m - 6md + 11n - nd
(7c4 - ƒ2)(11ƒ - c3) = 77c4ƒ - 7c4c3 - ƒ2*11ƒ + ƒ2c3
(a + 9x)(a2 + ax - x2) = a(a2 + ax - x2) + 9x(a2 + ax - x2)
(11n2m3 + 2n3m3)(5n3m2 - 3m2) = 55n5m5 - 33n2m5 + 10n6m5 - 6n3m5

Question 2

1. (x + k) (m + n) - 2. (6m + n)(11 − d) 3. (7c4 — ƒ2) (11ƒ – c3) 4. (a + 9x) (a2 + ax − x2) 5. (11n2m3 + 2n3m3) (5n3m2 – 3m2(

Answer

1. (x + k) (m + n) = xm + xn + km + kn 2. (6m + n)(11 − d) = 66m - 6md + 11n - nd 3. (7c4 - ƒ2)(11ƒ - c3) = 77c4ƒ - 7c4c3 - ƒ2*11ƒ + ƒ2c3 4. (a + 9x)(a2 + ax - x2) = a(a2 + ax - x2) + 9x(a2 + ax - x2) 5. (11n2m3 + 2n3m3)(5n3m2 - 3m2) = 55n5m5 - 33n2m5 + 10n6m5 - 6n3m5
