Answer: x^2 + 4x + 4
Explanation:
just expand, factor out, and add together.
(x+2)(x+2)
x • x = x^2
2x + 2x = 4x
2 • 2 = 4
x^2 + 4x + 4
Answer:
A. n = 5
Step-by-step explanation:
S = n² + n
When S = 30:
n² + n = 30
Subtract 30 from both sides: n² + n - 30 = 0
Factorize: (n - 5)(n + 6) = 0
Therefore n = 5 or -6
As n > 2, then n = 5 only
