10y-50=<br> 10y−50=<br> \,\,-20<br> −20
densk [106]

Answer:

Therefore the value of 'y' is,

y=3

Step-by-step explanation:

Given:

10y-50=-20

To Find:

y= ?

Solution:

10y-50=-20    ........Given

Step 1. Adding 50 to both the side we get

10y-50+50=-20+50\\10y=30

Step 2. Dividing by 10 on both the side we get

\dfrac{10y}{10}=\dfrac{30}{10}\\\\y=3

Therefore the value of 'y' is,

What is the completely factored form of x4 8x2 – 9?
Alinara [238K]

For this case we have the following polynomial:

x ^ 4 + 8x ^ 2 - 9

We make the following change of variables:

u = x ^ 2

Rewriting we have

u ^ 2 + 8u - 9

Factoring the second order polynomial we have:

(u + 9) (u-1)

Then, returning the change we have:

(x ^ 2 + 9) (x ^ 2-1)

Finally, we factor the expression in the parentheses of the second term:

(x ^ 2 + 9) (x + 1) (x-1)

Answer:

the completely factored form is:

(x ^ 2 + 9) (x + 1) (x-1)
