Janelle built a catapult to launch snowballs at her brother for their epic snowball fight. She wants to
figure out how long her snowballs will be in the air for before they land, so she develops the quadratic
expression below in which "t" represents time after launch in seconds). How many seconds after launch
will it take for her snowballs to land back on the ground?

Ответ:
Both Jared and Nicole are correct. You can solve for either variable and use the equivalent expression to create a one-variable equation. Then you can solve. Jared would have created a one-variable equation that can be used to solve for x, whereas Nicole would have created a one-variable equation that can be used to solve for y.
