Hopefully this helped. :)

Answer quick find the coordinates

Mekhanik [1.2K]

Answer:

(-4, -3), (4, -1), (8, 0), (12, 1)

Step-by-step explanation:

The x- and corresponding y-values are listed in the table. Put each pair in parentheses, x-value first. (That is an ordered pair.)

(x, y) = (-4, -3) . . . . from the first table entry

(x, y) = (4, -1) . . . . from the second table entry

(x, y) = (8, 0) . . . . from the third table entry

(x, y) = (12, 1) . . . . from the last table entry

Use FOIL to explain how to find the product of (a + b)(a − b). Then describe a shortcut that you could use to get this product w

andriy [413]

Greetings!

FOIL stands for:

Front
Outside
Inside
Last

This tells which terms to multiply when using the Distributive Property.
(NOTE: Only applicable with 2-term Polynomials)

For Example:
$(a+b)(a-b)$

Multiply the Fronts of both Equations:
$(a*a)$

Multiply the Outsides of both Equations:
$(a*a)+(a*-b)$

Multiply the Insides of both Equations:
$(a*a)+(a*-b)+(b*a)$

Multiply the Lasts of both Equations:
$(a*a)+(a*-b)+(b*a)+(b*-b)$

Simplify.
$=a^2-ab+ba-b^2$

$=a^2-b^2$

Alternative Method (My Prefered Method)
$(a+b)(a-b)=a(a+b)-b(a+b)$

Use Regular Distributive Property.
$a(a+b)-b(a+b)$

$a*a+a*b-b*a+-b*b$

Simplify.
$a^2+ab-ba+-b^2$

$a^2-b^2$

Hope this helps.
