Find the complete factored form of the polynomial -8a^4b^5+4a^2b^4

Zigmanuir [339]

Answer:

The completely factored polynomial is:

⇒ $-4a^2b^4(2a^2b-1)$

Step-by-step explanation:

Given polynomial:

$-8a^4b^5+4a^2b^4$

To factor the given polynomial completely.

Solution:

In order to factor the given polynomial, we will find the greatest common factor of the terms and then factor them out by dividing the term by its G.C.F.

The factors can be listed as:

$-8a^4b^5=-1\times 2\times 2\times 2\times a\times a\times a\times a\times b\times b \times b\times b \times b$

$4a^2b^4=2\times 2\times a\times a\times b\times b \times b\times b$

From the factors listed the GCF can be given as = $2\times 2 \times a\times a \times b \times b\times b \times b$

GCF = $4a^2b^4$

Factoring out the GCF.

$4a^2b^4(-2a^2b+1)$

The above expression can be simplified by factoring out -1.

$-4a^2b^4(2a^2b-1)$ (Answer)

never [62]

Answer:

d = 6

Step-by-step explanation:

3(2d-8)=11d-18(d-3)

6d - 24 = 11d -18d +54

6d-11d+18d = 24+54

13d = 78

d = 6

How many grams are 2.7x10-^4 grams

andrew-mc [135]

Answer:

0,00027 grams!

Step-by-step explanation:

This is a scientific notation problem.

When a number is followed by a $10^{-1}$ , it means that said number has one zero at the beginning.

In this case, the number is followed by $10^{-4}$ , so that means that 2.7 has four zeros at the beginning. So, 2.7x $10^{-4}$ grams is equal to 0,00027 grams! (always the comma goes after the first zero).
