Question

X+9 x+9

1


Pls help me

Answer 1

Explanation:

Assuming you meant to write (x + 9) * (x + 9), this is a multiplication of two binomials, which can be expanded using the FOIL method:

(x + 9) * (x + 9) = x^2 + 9x + 9x + 81

Simplifying further, we can combine like terms:

x^2 + 18x + 81

Therefore, (x + 9) * (x + 9) = x^2 + 18x + 81.
