This one is very similar to the previous example. Here is the work for this problem. y (1 + 8 x ) = 4 - 3 x
y + 8 xy = 4 - 3 x
8 xy + 3 x = 4 - y x ( 8 y + 3) = 4 - y
x= 4- y
8y + 3 As mentioned at the start of this section we won’t be seeing this kind of problem all that often in
this class. However, outside of this class (a Calculus class for example) this kind of problem
shows up with surprising regularity. © 2007 Paul Dawkins 84 http://tutorial.math.lamar.edu/terms.aspx College Algebra Quadratic Equations – Part I
Before proceeding with this section we should note that the topic of solving quadratic equations
will be covered in two sections. This is done for the benefit of those viewing the material on the
web. This is a long topic and to keep page load times down to a minimum the material was split
into two sections.
So, we are now going to solve quadratic equations. First, the standard form of a quadratic
equation is ax 2 + bx + c = 0 a¹0 The only requirement here is that we have an x 2 in...
