Question

14(3y-5z)(3y-5z)(3y-5z)+7(3y-5z)(3y-5z)

Answer 1

Answer:

(3y - 5z)²(6y - 10z + 1)

Step-by-step explanation:

14(3y-5z)(3y-5z)(3y-5z)+7(3y-5z)(3y-5z)

Since (3y - 5z) repeats twice in every term, we put them together:

14(3y-5z)²(3y-5z)+7(3y-5z)²

Taking out common factors 7(3y - 5z)²:

7(3y - 5z)²( 2 (3y - 5z) + 1)

Distribute 2:

(3y - 5z)²(6y - 10z + 1)

Answer: (3y - 5z)²(6y - 10z + 1)
