The solution is -0.609611 and -1.64, I do not think you can simply find this by factoring but the only way is graphing it
Some expressions are:
7 times 4 equals 28
20 plus 8 equals 28
10 plus 18 equals 28
25 plus 3 equals 28
Answer: function b has a greater rate of change
we need the graph/ lines,
but just remember
wherever 2 lines intersect, that is a solution
if they are paralell, no solutions
if they cross, 1 solution
if they are the same line/ the lines are on top of each other exactly, infinite solutions
