Factories the expressions-
x (y + z) – 5 (y + z)

In the given expression

Take out the common in all the terms,

⇒ x (y + z) – 5 (y + z)

⇒ (y + z)(x - 5)

Hence the factors of x (y + z) – 5 (y + z) are (y + z) and (x - 5)

Factories the expressions-

6ab – b² + 12ac – 2bc

Factories the expressions-

p²q – pr² – pq + r²

Factories the following

x⁴ – y⁴

Factories the following

a⁴ – (b + c)⁴
