Add these fractions, giving your answer<br> in its simplest form.<br> 8/15 +3/15 =?

Mademuasel [1]

Answer:

11/15

Step-by-step explanation:

To add fractions, you add the numerators together( the top) and the bottom stays the same for this situation.

so the numerators of the fraction are 8 and 3

8+3 =11

So the answer is 11/15 and this is the most simplified it can get.

Which polynomial can be factored using the binomial theorem? 343x^3 – 441x^2 + 567x – 729 343x^3 – 882x^2 + 1,134x – 729 1,296x^

algol [13]

Answer:

1,296x^4 – 864x^3 + 216x^2 – 24x + 1

Step-by-step explanation:

From binomial theorem we know that:

$(a + b)^4 = a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4$

$a^4 = 1,296x^4 = (6x)^4$

a = 6x

$b^4 =1$

b = -1 or b = 1

We have to satisfy: $4ab^3 = -24x$ . Using b = -1

$4(6x)(-1)^3 = 24x(-1) = -24x$

We have to satisfy: $4a^3b = -864x^3$

$4(6x)^3(-1) = (-4)216x^3 = -864x^3$

We have to satisfy: 6a^2b^2 = 216x^2

$6(6x)^2(-1)^2 = 6(36)x^2 = 216x^2$

Then, $(6x - 1)^4 = 1,296x^4 - 864x^3 + 216x^2 - 24x + 1$
