Answer:
a) The estimates for the solutions of
are
and
.
b) The estimates for the solutions of
are
and
Step-by-step explanation:
From image we get a graphical representation of the second-order polynomial
, where
is related to the horizontal axis of the Cartesian plane, whereas
is related to the vertical axis of this plane. Now we proceed to estimate the solutions for each case:
a) 
There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:
,
b) 
There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:
,
It's called a rectangle. This is just a definition, so there is not much to explain.
