$x^{4}-x^{2}y^{2}-2y^{4}$
$=x^{4}-2x^{2}y^{2}+x^{2}y^{2}-2y^{4}$
$=x^{2}(x^{2}-2y^{2})+y^{2}(x^{2}-2y^{2})$
$=(x^{2}-2y^{2})(x^{2}+y^{2})$

Please help me, I’ve literally been trying for so long.

Let the cosecutive numbers be like this :

2n + 1 , 2n + 2 , 2n + 3 , 2n + 4 , 2n + 5

Odd , Even , Odd , Even , Odd

______________________________

So we have :

(2n+1)+(2n+3)+(2n+5)=(2n+2)+(2n+4) + 39

6n + 9 = 4n + 6 + 39

6n + 9 = 4n + 45

Subtract both sides 9

6n + 9 - 9 = 4n + 45 - 9

6n + 0 = 4n + 36

6n = 4n + 36

Subtract both sides 4n

6n - 4n = 4n - 4n + 36

2n = 0 + 36

2n = 36

Divide both sides by 2

2n ÷ 2 = 36 ÷ 2

n = 18 

______________________________

So the numbers are :

2(18)+1 , 2(18)+2 , 2(18)+3 , 2(18)+4 , 2(18)+5

36 + 1 , 36 + 2 , 36 + 3 , 36 + 4 , 36 + 5

37 , 38 , 39 , 40 , 41

As u can see the Odd numbers are :

37 , 39 , 41

And we're done ...

Solve the following equation, answer as a reduced, mixed number. 4(3 - 2x) = 15

Inessa05 [86]

Start by distributing the 4:
12-8x=15
Add 8x to both sides of the equation and subtract 15 from both sides:
8x=-3
divide both sides by 8 to get the value of x:
x=-3/8
