Question 1 : pg 175
The
Which of the following represents the statement "the sum of the squares of x and y is equal to the square root of the difference of x and y" ?
A. x^2 + y^2 =
B. x^2 − y^2 =
C. (x + y)^2 =
D. = (x − y)2
Test
Strategies
& How to solve
Step 1
Step 2
Read & Evaluate the question it states to use the "sum" so you will begin by adding. You will add the "squares of x and y"
Being that you will add x^2 +y^2 that has to be in the equation or answer choice so any choice that doesn't have that you can Eliminate. So
that only leaves one choice A.
What we did ?
You saved time while taking the test by using these Strategies !
Instead of trying to instantly solve the problem we Read & Evaluated and solved partial of the problem and then Eliminated choices that weren't included in the answer we got so far.
Question #4
PLAN
If a=-2, then a + a^2 -a^3 +a^4 -a^5=
A.)-22
B.)-18
c.)32
D.58
How to Solve
How To Solve Problem
You solve this by plugging in the number given for (a) in the expression to find the value :-2+(-2)^2-(-2)^3+(-2)^4-(-2)^5.
Mnemonic Device
Value plugged in or (a)
Remember "PEMDAS" the order of operations:the first thing to do here is deal with the exponents, then we can take care of the addition and subtraction -2+4-(-8)+16-(-32), which simplfies to -2+4+8+16+32=58. Which is answer (D).
Step 1
Step 2
Read & Evaluate and the first thing you have to do is substitute or plug in the given value which was -2.
The second strategy to solving this problem efficiently was to use PEMDAS a mneomic device that
lets us know which order in which we solve the problem.
What we did ?
You read thoroughly & used a mnemonic device to solve the problem in a timely manner !
Instead of trying to instantly solve the problem we Read & Evaluated and solved partial of the problem and then Eliminated choices that weren't included in the choices.
