Hi @pitachips - please only ask one question at a time. Also, be sure to try and learn the material (if you learn how to do the first question, you should be able to do the rest on your own in this case). Thanks.

$$y=16x+40x+25$$ is not quadratic

anonymous · Answer

use the quadratic formula. just plug in the coefficients into the formula read this short tutorial - http://www.purplemath.com/modules/quadform.htm
