What is the completely factored form of 12xy – 9x – 8y + 6? (3x – 2)(4y – 3) 3x(4y – 3) – 2(4y + 3) –6x(4y – 3)(4y – 3) (3x – 2)
2 answers:
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
We just need to find the factors of the polynomial with two variables.
1) Taking the common factor from first two terms i.e. 3x
So, it becomes,
2) Now, taking the common factor from last two terms i.e. -2
So, it becomes,
So, Combined form will be given as
Hence, First option is correct.

Explanation:
Logarithms are used to solve exponential equations. Specifically if you have a variable in the exponent, then you use a log to isolate the variable.
If we set the given log expression to x, then we can rewrite it into 8^x = 1. The only value of x that works is x = 0.
------------
Or put another way,
8^x = 1
8^x = 8^0 ... replace the 1 with 8^0
x = 0 ... the bases are equal (to 8) so the exponents must be equal
------------
You can use the change of base formula to directly calculate this log
