Answer:
\(16x^2y^2-24xyz +9z^2\)
Step-by-step explanation:
\((4xy - 3z)^2\)
Given expression has exponent 2, so we multiply it twice
\((4xy - 3z)(4xy-3z)\)
Apply FOIL method to multiply the parenthesis
multiply 4xy inside the second parenthesis
and multiply -3z inside the second parenthesis
\(4xy(4xy-3z)=16x^2y^2-12xyz\)
\(-3z(4xy-3z)=-12xyz+9z^2\)
\(16x^2y^2-12xyz-12xyz+9z^2\)
Combine like terms
\(16x^2y^2-24xyz +9z^2\)
