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

xenn [34]

Answer:

The product of (a+b)(a-b) is $a^2 - b^2$

Step-by-step explanation:

Use FOIL to explain how to find the product of (a + b)(a − b)

FOIL is

Multiply First terms : a*a = a^2

Multiply Outside terms : a* -b = -ab

Multiply Inner terms : b * a= ab

Multiply last terms : b * -b = -b^2

now we combine all the terms

$a^2 -ab+ab - b^2$

combine like terms

$a^2 - b^2$

The product of (a+b)(a-b) is $a^2 - b^2$

Shortcut is we apply an identity

$a^2 - b^2 = (a+b)(a-b)$

Find the coordinates of

alexira [117]

Answer:(6,-2)

Step-by-step explanation:

M is the midpoint of AB then ,

M = $\frac{A+B}{2}$

$5=\frac{x+4}{2}$ , $-2=\frac{y-2}{2}$

$10=x+4$ , $-4=y-2$

$x=6$ , $y= -2$

so, B= (6,-2)

What is the value of y + 25 equals 3 y -2

cluponka [151]

First subtract y from both sides to isolate the variable.

25 = 2y-2

Next, add 2 to both sides.

27 = 2y

Last, divide by 2.

13.5 = y
