Answer:

Hope it helps you.............

Step-by-step explanation:

Given -

m²(m + 2n)(m - 4n)

First we solve \textbf{(m + 2n)(m - 4n)}(m + 2n)(m - 4n)

Using identity -

(x + a)(x + b) = x² + (a + b)x + ab

Here, x = m, a = 2n and b = - 4n

•°•

(m + 2n)(m - 4n) =

= m² + [(2n) + (- 4n)] (m) + (2n)(- 4n)

= m² + (- 2n)(m) + (- 8n²)

= m² - 2mn - 8n²

Now, Back to the question

So, we can write

m²(m² - 2mn - 8n²)

= m⁴ - 2m³n - 8m²n²

Sorry but copied from brainly website .

SO SORRY

Step-by-step explanation:

m^2(m^2-4mn+2mn-8n^2)

m^2(m^2-2mn-8n^2)

m^4-2m^3n-8m^2n^2

m^4+2m^3n-4m^3n-8m^2n^2

m^3(m+2n)-4m^2n(m+2n)

(m^3-4m^2n)(m+2n).
