Example 1:

Polynomials are algebraic expressions that contain more than one term. You will definitely have questions on the exam about multiplying polynomials.

algebra-questions-1

Solution 1:

When multiplying polynomials, you should use the F-O-I-L method.

This means that you multiply the variables two at a time from each of the two parts of the equation in the parentheses in this order:

First – Outside – Inside – Last

So, the first variables in each set of parentheses are 2x and 2x

FIRST:

algebra-questions-3

The variables on the outside of each set of parentheses are 2x and 3y

OUTSIDE:

algebra-questions-4

The variables on the inside of each set of parentheses are -3y and 2x

INSIDE:

algebra-questions-5

The last variables in each set of parentheses are -3y and -3y

LAST:

algebra-questions-6

Then we add all of the above parts together to get:

algebra-questions-8

Example 2:

Algebra questions on the Accuplacer Test will also include inequalities problems. Inequalities contain the less than or greater than signs.

31 – 2/3x > 27, then x < ?

Solution 2:

In order to solve inequalities, deal with the whole numbers on each side of the equation first:

31 – 2/3x > 27

(31 – 31) – 2/3x > (27 – 31)

2/3x > -4

Then deal with the fraction:

2/3x > -4

3 × –2/3x > -4 × 3

-2x > -12

Then deal with the remaining whole numbers:

-2x > -12

-2x ÷ 2 > -12 ÷ 2

-x > -6

Then, deal with the negative number:

-x > -6

-x + 6 > -6 + 6

-x + 6 > 0

Finally, isolate the unknown variable as a positive number:

-x + 6 > 0

– x + x + 6 > 0 + x

6 > x

x < 6
