ALGEBRA 2 6.0
TEST ON SECTIONS 4-4, 4-5, 4-6, and 4-8
MONDAY, DECEMBER 21st (WITHOUT a calculator)
TUESDAY, DECEMBER 22nd (WITH a calculator)
(Problems involving computation of complex numbers or
graphing will be given on Monday. Word problems will be given
on Tuesday. Other topics could be on either day)
This assessment will cover the rest of Chapter 4. It will assume a mastery
of the material from Sections 4.1 - 4.3 and 4.7 with an emphasis on the new
material from Sections 4-4 to 4-6 and 4-8. In addition to the objectives
for the last test you should be able to do the following:
 Solve a quadratic equation by completing the square. Remember that
you can only complete the square if the coefficient of x 2 is 1.
 Define i as 1 but never use 1 in an expression, only i
 Simplify any power of i as much as possible. Use the facts that any
multiple of i 4 equals 1, i3  i , and i 2  1 .
 Write any complex number in standard form, a + bi
 Identify the complex conjugate of a complex number and use it to
simplify denominators of fractions with imaginary numbers
 Add, subtract, multiply, and divide complex numbers, giving answers in
standard form, a + bi.
 Given 2 equal complex numbers written in terms of a variable, solve
for the variable by setting the real parts equal to each other and the
imaginary parts equal to each other.
 Put ANY quadratic equation into standard form, ax2  bx  c  0 ,
(identifying a, b, and c) and use the quadratic formula to determine
its roots ( imaginary or real). Know the perfect squares (1, 4, 9, 16,. . .)
so that you can use them as factors to simplify the radicals. Find
exact solutions in simplified form without a calculator. If requested,
round answers to the nearest hundredth using a calculator
 Understand that quadratic equations must have 0, 1 or 2 real roots.
Be able to draw a rough sketch of a quadratic equation that has a
given number of roots.


Given two root(s) (real or imaginary) determine a quadratic equation
that has those roots.
Determine the discriminant of a quadratic equation and use it to
describe the roots (number of roots, real, imaginary, rational,
irrational. Remember - only real numbers are rational or irrational)
Solve quadratic inequalities in one variable both algebraically and
graphically. Algebraic solutions require a chart. Graphic solutions
require a rough sketch of a parabola.
Graph the solution of a quadratic inequality in two variables.
Remember that the solution is a set of ordered pairs represented by
the shaded region.
Have a clear understanding of the difference between inequalities of
the form y < ax2 + bx + c (solution is a set of ordered pairs and must
be graphed) and 0 < ax2 + bx + c (solution is a set of real numbers and
can be described using interval notation).
Use your knowledge of quadratic functions to solve word problems
involving concepts such as, but not limited to, objects thrown or
launched into the air or dropped from above, maximum or minimum
values for area, profit, revenue, or cost. For each problem be able to
define the variable(s) and write the equation or inequality to be used
to solve the problem, You may use any method to solve the equation or
inequality. Depending on the directions, you must show your work or
describe briefly what you did on the calculator (i.e, found the xintercepts, found the maximum value from the vertex, found the
intersection of the two graphs.)
