Question

Choose whether the expression is a result of multiplying

Answer 1

The given expression is a result of squaring binomials

Factoring quadratics

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
