Question

Q3) Write the following as a square of binomial:
9m⁴ - 30 m²n + 25n²​

Answer 1

Answer:

(3m^2-5n)^2

Step-by-step explanation:

• 9m^4 - 30m^2n + 25n^2

This polynomial can be written as

• (3m^2)^2 - 2×3m^2×5 + (5n)^2

This in the form of (a - b)^2=a^2 - 2ab + b^2, where a=3m^2 , b=5n

Therefore, (3m^2 - 5n)^2=(9m^4 - 30m^2×n + 25n^2)
