Which expression does not factor? m3 + 1 m3 – 1 m2 + 1 m2 – 1

Luda [366]

Answer:

$m^2 +1$

Explanation:

All the other expressions can be factorized. Let's see why:

1) $m^3 +1$

This is the sum of the cubes, and this can be factorized as follows:

$a^3+b^3=(a+b)(a^2-ab+b^2)$

In this case, a=m and b=1, so we can factorize as

$m^3+1=(m+1)(m^2-m+1)$

2) $m^3-1$

This is the difference between two cubes, and this can be factorized as follows:

$a^3-b^3=(a-b)(a^2+ab+b^2)$

In this case, a=m and b=1, so we can factorize as

$m^3-1=(m-1)(m^2+m+1)$

3) $m^2-1$

This is the difference between two square numbers, and it can be factorized as follows

$(a^2-b^2)=(a+b)(a-b)$

In this case, a=m and b=1, so we can factorize as

$m^2-1=(m+1)(m-1)$

Solve the logarithmic equation. When necessary, round answer to the nearest hundredth. log 3(x + 4) - log 3(x + 2) = log 327

alexandr1967 [171]

Answer:

$x = -\dfrac{25}{13}$

Step-by-step explanation:

$\log_3{x + 4} - \log_3{x + 2} = \log_3 {27}$

$\log_3 \dfrac{x + 4}{x + 2} = \log_3 {27}$

$\dfrac{x + 4}{x + 2} = 27$

$x + 4 = 27(x + 2)$

$x + 4 = 27x + 54$

$-26x = 50$

$x = -\dfrac{50}{26}$

$x = -\dfrac{25}{13}$
