The product of the sum of two perfect cubes:

a³ + b³ = (a + b)(a² - ab + b²)

The product of the difference of two perfect cubes:

a³ - b³ = (a - b)(a² + ab + b²)

----------------------------------------------------------------------------------------------------------------

Remember to follow FOIL:

(b^2 + 8)(b^2 - 8)

(b^2)(b^2) = b^4

(b^2)(-8) = -8b^2

(8)(b^2) = 8b^2

(8)(-8) = -64

b^4 - 8b^2 + 8b^2 - 64

Combine like terms:

b^4 (-8b^2 + 8b^2) - 64

b^4 - 64

b^4 - 64 is your answer

hope this helps

Find the solutions to the equation 4x2 - 8x + 3 = 0

katovenus [111]

<h2>Steps</h2>

So to find the solutions, I will be factoring by grouping. Firstly, what two terms have a product of 12x² and a sum of -8x? That would be -2x and -6x. Replace -8x with -2x - 6x:

$4x^2-2x-6x+3=0$

Next, factor 4x² - 2x and -6x + 3 separately. Make sure that they have the same quantity on the inside of the parentheses:

$2x(2x-1)-3(2x-1)=0$

Now you can rewrite it as:

$(2x-3)(2x-1)=0$

Now, apply the zero product property and solve:

$2x-3=0\\2x=3\\x=\frac{3}{2}\ \textsf{OR}\ 1.5\\\\2x-1=0\\2x=1\\x=\frac{1}{2}\ \textsf{OR}\ 0.5$

<h2>Answer</h2>

<u>In short, x = 3/2 (1.5) and 1/2 (0.5).</u>

A hockey goalie loses 2 3/5 rating points each time his team loses. If his team loses 8 games in a row, what number represents t

adelina 88 [10]

Answer:

$20\frac{4}{5}$

Step-by-step explanation:

We have been given that a hockey goalie loses 2 3/5 rating points each time his team loses. His team loses 8 games in a row.

To find the number that will represent the change in goalie's ratings after losing 8 games we will multiply 8 by $2\frac{3}{5}$ .

$8*(2\frac{3}{5})$

Let us convert our mixed fraction into improper fraction.

$8*\frac{13}{5}$

$\frac{8*13}{5}$

$\frac{104}{5}$

$20\frac{4}{5}$

Therefore, $20\frac{4}{5}$ will represent the change in the goalie's rating points.
