Question

11)expand - (5p-4)2 ​

Answer 1

Answer:

25p² + 16 - 40p

Step-by-step explanation:

(5p - 4)²

(a - b)² = a² + b² - 2ab

(5p - 4)²

= (5p)² + (4)² - 2(5p)(4)

= 25p² + 16 - 40p

Answer 2

Step-by-step explanation:

(5p -4)^2

Expanding using id.

(a- b)^2 = a^2 + b^2 - 2ab

= (5p)^2 + 4^2 - 2(5p) (4)

= 25 p^2 + 16 - 40 p

☆Standardizing the polynomial

25p^2 - 40p + 16
