Question

Explain why x²+25 is not equal to (x + 5)²

The expressions are not equal because when the expression (x + 5)2 is written as the product (x+5)(x + 5) and expanded, it is necessary to apply the
leading to a(n)
that is missing from the expression x² +25

Answer 1

The expressions x²+25 and (x + 5)² are not equal because (x + 5)² can be expanded as (x+5)(x + 5), which results in x² +10x + 25. So, the missing term in x²+25 is 10x.

Step-by-step explanation:

The expressions x²+25 and (x + 5)² are not equal because (x + 5)² can be expanded as (x+5)(x + 5), which results in x² +10x + 25. So, the missing term in x²+25 is 10x. Thus, x²+25 is not equal to (x + 5)².
