SIXTH GRADE / ALGEBRAIC EXPRESSIONS / TEST 4.1.1

MATHEMATICS IS EASY. PROVIDED THAT ONE WORKS ENOUGH.
ENOUGH IS SKILL DEPENDENT, HAVE TO FIND "ENOUGH" FOR YOUR SIZE.

SOME OF OUR QUESTIONS ARE REALLY HARD, FOR THOSE THAT ARE SKILLED IN MATH.
SKIP THEM IN CASE NOT FOR YOU.

IF YOU DESIRE SO, WE CAN DISCUSS HARD/INTERESTING QUESTIONS IN OUR FORUM.

 Algebraic Expressions

    ♦ 
We somehow knew these days would come, so we used these kind of expressions before.
    ♦ Whenever we used a character like "A", "b", "♦" etc. instead of a number, we happened to have written down an algebraic exprssion indeed.
    ♦ We need to inform that the algebaric expressions use tradionally a, b,c ... (the first letters of the alphabet) for coefficients and ... x,y,z for the variables. In addition we will not use "x" for product sign, it is from now on a variable.

    Ref.-1
    Ref.-2
1. Which are the coefficients of the expression a2·x2 + a1·x + a0 ?

a) a, b and c
b) a2, a1 and a0
c) x and a1
d) all
You will soon see why of our notation .
2. What will be the evaluation of the algebraic expression 3·x2 + 2·x + 1 for x = 3 ?

a) 33
b) 41
c) 28
d) 34
3·32 + 2·3 + 1 = ? .
3. What will be the evaluation of the 2dn term of the algebraic expression 3·x2 + 2·x + 1 for x = 5 ?

a) 0
b) 1
c) 5
d) 10
Added or subtracted numbers/variables each are called terms, if multiplied then factors. So the second term is 2·5 for x=5.
4. For which value of x is the statement 2·x + 5 = 0 a true statement ?

a) - 5/2
b) 5/2
c) 2/5
d) - 2/5
2·x + 5 - 5 = 0 - 5 => 2·x = - 5 .
5. Which set is the intersection of the solution set of the statement 2·x + 5 = 0 and the set of natural numbers ?

a) {-5/2}
b) -5/2
c) ∅
d) none
Solution set is {-5/2} .
y
6. What is the solution set to 9·x2 - 81 = 0 ?

In case of need for tips get the cursor on "y" or for help click at "ry1/2" .
RY1 RY2



a) {3}
b) {3,-3}
c) {-3}
d) {1,3}


Solution set is the set of values for which the statement is true.
Division of both sides of the statement by 9 gives ·x2 - 9 = 0 .

!


a) 0.003
b) 1.003
c) 1

Kids, you may need to consider;
1- The tree may live 5-50 times longer than a cottage.
2- A university education, if possible a PhD, will help you understand natural phenomena better.
3- You may need to form unions in order to increase your individual strength.
4- Something may be lacking, something not mentioned here may be lacking since we seem to be behind Chief Seattle and on the way to realize his predictions in spite of all our education.
