We'll calculate the product:
[tex](-2m+5n)^2=(-2m+5n)(-2m+5n)\\\\ (-2m+5n)^2=(-2m)\cdot(-2m+5n)+(5n)(-2m+5n)\\\\ (-2m+5n)^2=[(-2m)\cdot(-2m)+(-2m)\cdot(5n)]+[(5n)\cdot(-2m)+(5n)\cdot(5n)]\\\\ (-2m+5n)^2=4m^2-10mn-10mn+25n^2\\\\ (-2m+5n)^2=4m^2-20mn+25n^2[/tex]
So, the answer is:
[tex]4m^2-20mn+25n^2,~\text{a perferct square trinomial.}[/tex]
[tex](-2m+5n)^2=(-2m+5n)(-2m+5n)\\\\ (-2m+5n)^2=(-2m)\cdot(-2m+5n)+(5n)(-2m+5n)\\\\ (-2m+5n)^2=[(-2m)\cdot(-2m)+(-2m)\cdot(5n)]+[(5n)\cdot(-2m)+(5n)\cdot(5n)]\\\\ (-2m+5n)^2=4m^2-10mn-10mn+25n^2\\\\ (-2m+5n)^2=4m^2-20mn+25n^2[/tex]
So, the answer is:
[tex]4m^2-20mn+25n^2,~\text{a perferct square trinomial.}[/tex]
The concept of the square is applied that is the multiplication of the term itself two times.
The equivalent function of [tex]\rm (-2m + 5n)^2[/tex] is [tex]\rm 4m^2 - 20mn + 25n^2[/tex].
What is an equivalent function?
The equivalent is the functions that are in different forms but are equal to the same value.
Given
(-2m + 5n)² is a function.
To find
The equivalent function of (-2m + 5n)².
We know that this can be written as
(-2m + 5n) x (-2m + 5n)
On multiply, we have
[tex]\rm (-2m + 5n)(-2m + 5n)\\\\-2m(-2m + 5n) + 5n(-2m + 5n)\\\\(-2m)^2 - 10mn -10mn + (5n)^2\\\\4m^2 - 20mn + 25n^2[/tex]
Thus, the equivalent function of (-2m + 5n)² is 4m² - 20mn + 25n².
