anonymous · Answer

Im doing perfect trinomials

anonymous · Answer

----+42z+49

anonymous · Answer

As in
$$(u + v)^{2} = u^{2} + 2 u v + v^{2} ?$$

anonymous · Answer

the directions say supply the missing term to make each expression a perfect square trinomial

anonymous · Answer

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 $$9 z^{2}.$$

anonymous · Answer

You can FOIL to verify that $$(3z + 7)^{2} = 9z^{2} + 42z + 49.$$
