Answer:

see below

Step-by-step explanation:

0 = x^2 + 6x – 10

Add 10 to each side

10 = x^2-6x

Take the coefficient of x

-6

Divide by 2

-6/2 =-3

Square it

(-3)^2 =9

Add 9 to each side

10+9 = x^2-6x+9

We use -3 for the square term

19 = (x-3)^2

Take the square root of each side

±sqrt(19) = x-3

Add 3 to each side

3±sqrt(19) = x

Find what n equals 8(2n-2) = 4 - 4n (explanation please)
slavikrds [6]

Answer:

\huge\boxed{n=1}

Step-by-step explanation:

In order to find the value of n that satisfies this equation, we can perform a series of algebraic steps on it to solve for n.

  • 8(2n-2) = 4- 4n
  • <em>Distribute in the 8 on the left side:</em>
  • <em />16n-16=4-4n<em> </em>
  • <em>Add 4n to both sides</em>
  • 20n-16=4
  • <em>Add 16 to both sides</em>
  • 20n = 20
  • <em>Divide both sides by 20</em>
  • n=1

Therefore, n=1 is the value of n that satisfies this equation.

Hope this helped!
