Solve using the quadratic formula: 2(x-1) = 2x - 2

0=0

Step-by-step explanation:

2(x−1)=2x−2

Step 1: Simplify both sides of the equation.

2(x−1)=2x−2

(2)(x)+(2)(−1)=2x+−2(Distribute)

2x+−2=2x+−2

2x−2=2x−2

Step 2: Subtract 2x from both sides.

2x−2−2x=2x−2−2x

−2=−2

Step 3: Add 2 to both sides.

−2+2=−2+2

0=0

X can be any real number

Step-by-step explanation:

2(x-1) = 2x - 2

Distribute

2x -2 = 2x-2

Subtract 2x from each side

2x-2x-2 = 2x-2x-2

-2 = -2

This is always true so there are infinite solutions

X can be any real number

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
