Question

how do you solve vertical motion equations without factoring?

Answer 1

Quadratic formula?

Answer 2

Graphing?

Answer 3

yes, i have been stuck on 0=-16t^2+80t+4

Answer 4

quadratic formula

Answer 5

you cant factor it and my teacher said we couldnt use quadratic formula

Answer 6

even though i did for one because i was so frustrated

Answer 7

You can graph by finding the vertex, y-intercept, and one other point.

Answer 8

cant you just solve for t without graphing?

Answer 9

I don't know of any other way.

Answer 10

same, oh well got use quadratic formula

Answer 11

But you would get the roots (x-intercepts) if you graph.

Answer 12

yes but you would have had to estimate

Answer 13

Try this, just so you know what the roots are.
