The given expression is a result of squaring binomials
<h3>Factoring quadratics </h3>
From the question, we are to determine whether the given expression is a result of multiplying conjugates together, squaring binomials, or neither
The given expression is
9z² +54z +81
To do this,
First, we will factor the expression
Factoring the expression
9z² + 54z + 81
First, factor out 9
9(z² +6z +9)
9(z² + 3z + 3z + 9)
9[z(z + 3) + 3(z + 3)]
9[(z +3)(z +3)]
9[(z +3)²]
This can further be expressed as
3²[(z +3)²]
[3(z +3)]²
(3z +9)²
Hence, the expression is a result of squaring binomials
