Mathematics

Jobisdone [24]3 years ago

Answer:

None.

Step-by-step explanation:

5/a - 2 / (1 - a) = 2 (a - 1)

Multiply each term by  a(1 - a)(a - 1):

5 (1 - a)(a - 1) - 2a(a - 1)  = 2a(1 - a)

5( a - 1 - a^2 + a)  - 2a^2 + 2a = 2a - 2a^2

5(-a^2 +  2a  - 1) - 2a^2 + 2a = 2a - 2a^2

-5a^2 + 10a - 5 - 2a^2 + 2a - 2a + 2a^2 = 0

-5a^2 + 10a - 5 = 0

-5(a^2 - 2a + 1) = 0

= -5(a - 1)^2 = 0

So a = 1.

But a = 1 cannot be a root because 2/ 1 - a would be 2/0 which is undefined.

Also 2 / (a - 1) is undefined.

1. Addition
nexus9112 [7]

Answer:

1. Exponent

2. Multiplication

3. Subtraction

4. Square root

5. Addition

6. Division?

<em>Note: I am not very sure about my answer because of two things. 1. The proper order for operating is PEDMAS (Parentheses, Exponent, Multiplication, division, addition, and subtraction). There is no Square root in that operation so I will consider it in the middle. 2. There is no division operation in this problem.</em>
