Answer 2

Answer:

2) a. 7x + 14xy

➩ 7x(1 + 2y)

∴ The answer of this question is 7x(1 + 2y)

b. 2n² + 3n

➩ n(2n + 3)

∴ The answer of this question is n(2n + 3)

c. a² + bc + ab + ac

➩ a² + ab + ac + bc

➩ a(a + b) + c( a + b)

➩ (a + b) (a + c)

∴ The answer of this question is (a + b) (a + c)

d. xy - pq + qy - px

➩ xy - px + qy - pq

➩ x(y - p) + q(y - p)

➩ (y - p) (x + q)

∴ The answer of this question is (y - p) (x + q)

e. 6ab - 9bc

➩ 3b(2a - 3c)

∴ The answer of this question is 3b(2a - 3c)

f. 24x³ - 36x²y

➩ 12x²(2x - 3y)

∴ The answer of this question is 12x²(2x - 3y)

g. 25mn² + 50m²n

➩ 25mn(n + 2m)

∴ The answer of this question is 25mn(n + 2m)

h. - 54a⁴ - 27a³

➩ - 27a³(2a + 1)

∴ The answer of this question is - 27a³(2a + 1)
