Question

(m-2n+p) whole square 2

Answer 1

Answer:

(m-2n+p) whole square 2

(m-2n+p)(m-2n+p)

m2-2nm+pm-2nm+4n2-2np+pm-2np+p2

m2+4n2+p2-4nm+2pm-4np

Well, it’s more of an expression.

First let’s put it into a more readable form:

(a-b+c)(a-b+c)

For this, we select a term, and multiply it with each term in the other bracket, and then repeat until all terms have been selected.

So we’ll have:

aa -ab + ac -ba + bb -bc +ca -cb +cc

Which can be rewritten into:

a² + b² + c² - 2ab - 2bc + 2ac

Or, if you like:

a² + b² + c² - 2(ab + bc -ac)
