SELECT NUMBER PRESS STO BUTTON SELECT VARIABLE PRESS ENTER
TO STO A VARIABLE SIMPLY
NOW LET’S PRACTICE
ONE VARIABLE ALGEBRA PROBLEM What
is the only positive solution for the equation? 2x²-7x-30=0
A. B. C. D.
5 6 7 8
TRY ANOTHER For
which of the following equations is x= -4 a solution?
A. B. C. D.
2x2 – 8 = 0 X2 - 8x +64 = 0 X2 _ 2x -15 = 0 2x2 + 2x – 24 = 0
Here’s a easy one What
is the value of the expression 2 ÷ x-4 when X = 2?
A. B. C. D.
32 16 8 -16
NOW YOU NEED TWO SOLUTIONS What
are two solutions for the equation
X2 - x = 20
A. B. C. D.
-4 and 5 4 and -5 -10 and 2 -2 and 10
Now you need to find an answer to make both sides equal Solve for x. 3 + 3x = 12 + x
You can do more than one variable Given the expression 4x2 - 3(y + 6) which of the following values for x and y will result in a value of -11?
A. B. C. D.
x = 2, y = 3 X = -2, y = 4 X= -1, y = 2 X = 1, y = 0
Sometimes you need to give a value to x Which of the following expressions is equal to 3x2 + 3( x – 3) + x + 10?
A. B. C.
Hint: Sto x as 2 and whatever answer you get must be same as answer a, b, c, or d.
D.
X2 + 9x + 1 3x2 + 4x +19 3x2 + 2x + 19 3x2 + 4x + 1
Try Another Simplify the expression: (6x4 + 7x – 5x3 ) – (4x4 – 2x3 + 3x)
C.
10x4 + 7x3 + 18x 2x4 + 7x3 + 4x 2x4 + 7x3 + 18x
D.
2x4 - 3x3 + 4x
A. B.
AND EVERY TEST WILL HAVA A FOIL Multiply (3x + 4)(2x – 5)
A. B. C. D.
6x2 6x2 6x2 6x2
- 9x + 20 - 7x – 20 + 9x – 20 - 20
And sometimes you need to give a value to x and y Simplify the expression 4x(2y) + 3y(2 - x)
A. B. C. D.
Hint: Get used to storing x=2 and y=3
8xy + 6y – 3x 5xy + 6y 11xy + 6y 8xy + 6y - x
Hint: Put your division problems in as a fraction! Simplify
A.
3x(x2 + 3) – 2x(x2 + 3) – (x2 + 3)
x2
+3
B. C. D.
x3 - 1 x3 - 3x – 1 3x – 1 x-1
Some Practice Problems that were on the GED READY Solve the equation for x. 3(x + 2) = 2(2 – x)
Yes the foil Multiply (2x + 4)(x - 4)
A. B. C. D.
2x2 2x2 - 16 2x2 + 12x – 16 2x2 - 4x - 16
And the two sets of coordinates What is the equation of the line that passes through the points (0,1) and (6,-2)?
Important to know your x and y values in your coordinates! Which point is the graph of the equation 3x – 2y = 6
A. B. C. D.
(3, 2) (2, 3) (4, 3) (3, 4)
Equation of Line
Takes some time but it’s worth it! Solve the equation for x 10x2 - 11x -6 = 0
ONE LIKE THIS WILL BE ON EVERY TEST What is the equation for a line that passes through points (10, 6) and (2, 2)? Hint: you must store your x value and get your y value. Must work for both coordinates.
A. B. C. D.
y = 2x + 7 y = 2x + 1 y = 1/2x + 7 y = 1/2x + 1
So will one like this What is the value of f(-3) ? f(x) = -2x + 3
Hint: Find an answer that will give your -3.
And a few suggestions Use
your scroll back feature on your calculator to prevent having to reenter expressions or equations. Make sure your student has the proper hand held calculator to take into the test.
I hope you have found this session helpful I
put together a booklet of ACEC’s 2014 GED test busters containing the type questions I believe will be on the new test. I have a package of bell ringer I put together a booklet on math for the GED 2014 Science and Social Studies. Talk to your Program Manager and I will be happy to come share this information with you!
