As in
\[(u + v)^{2} = u^{2} + 2 u v + v^{2} ?\]
OpenStudy (anonymous):
the directions say supply the missing term to make each expression a perfect square trinomial
OpenStudy (anonymous):
Suppose the first term is\[a^{2} z^{2}.\]
\[\sqrt{a^{2} z^{2} } = az,\]\[\sqrt{49} = 7,\]
2(az)(7) = 14az = 42 z. Solve for a to get a = 3. The blank-filler is \[(3z)^{2},\]or \[9 z^{2}.\]
OpenStudy (anonymous):
You can FOIL to verify that \[(3z + 7)^{2} = 9z^{2} + 42z + 49.\]

Thank you. Im getting off whenever youre back if you have time could you please help me?
