Answer:
Step-by-step explanation:
The area of a square is equal to the length of each side squared. So, this case, 3 x 3 (32) = 9 square meters.

Step-by-step explanation:
To factor binomials and trinomials in one variable, you look for the common factors in the terms
<h3>How to factor a binomial and trinomial?</h3>
Binomials are polynomials with two terms while trinomial have three terms.
For instance, we have:
- Binomial: x^2 - 4
- Trinomial = x^2 + 4x + 4
To factor x^2 - 4, we use the following steps:
x^2 - 4
Express 4 as 2^2
x^2 - 4 = x^2 - 2^2
Apply the difference of two squares
x^2 - 4 = (x - 2)(x + 2)
To factor x^2 + 4x + 4 we use the following steps:
x^2 + 4x + 4
Express 4x as 2x + 2x
x^2 + 4x + 4 = x^2 + 2x + 2x + 4
Factorize
x^2 + 4x + 4 = x(x + 2) + 2(x + 2)
Factor out x + 2
x^2 + 4x + 4 = (x + 2)x + 2)
Rewrite as:
x^2 + 4x + 4 = (x + 2)^2
