7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.

On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.

For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.

Find two consecutive even integers such that the square of the first, decreased by the second is 130

marta [7]

Let's make the first even integer m and the second even integer n. The square of the first, decreased by the second is 130 is:

$m^{2}$ -n=130 ---> Add n to each side
$m^{2}$ =130+n ---> Take the square root of each side
m=± $\sqrt{130+n}$

Let's look at the first square number above 130, which is $12^{2}$ . <em>m</em> is 12, therefore the next consecutive even integer is 14.

$12^{2}$ =144
144-14=130

The two consecutive integers are 12 and 14
