The bird feeder on a pole measures +6 feet and there is a buried treasure chest at -4 feet. 0 is ground level. Determine which item is closer to ground level. 0ω0 I don't get this-
..-at all

the answer is 4

just think of -4 as 4 in this question it is looking for the one closer and now that both of them are counting numbers 4 is less

We assume before this you have learned how to multiply two monomials and monomial with binomial.

Use the following formula to multiply binomials:

(a + b)(c + d) = ab + ad + bc + bd

Applied to the given expression, we have:

(x + 2)(x - 4), where a = x, b = 2, c = x , d = -4

Expand as indicated above:

(x + 2)(x - 4) =x(x) + x(-4) + 2(x) + 2(-4)

Now simplify

x² - 4x + 2x - 8

Collect like terms, (-4x) and (2x):

x² + (-4x + 2x) - 8 = x² - 2x - 8

This is how you can do same order operations with any binomials.
