The square of a binomial expands as follows:

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

Expanding all the binomials, we have

$4k^2-36k+81+k^2+4k+4=4k^2+4k+1+k^2-16k+64$

Sum like terms:

$5k^2-32k+85=5k^2-12k+65$

Simplify terms appearing on both sides:

$-32k+85=-12k+65$

Move all terms involving k to the left and all numbers to the right:

$-20k=-20$

Divide both sides by -20:

$k=1$

Answer:

1250 p² x¹² y³z⁶m⁵

Step-by-step explanation:

5x²y³z⁵m²(-2p²m³zx⁴)(-5x²)³

5x²y³z⁵m²(-2p²m³zx⁴)(-125x⁶)

5x²y³z⁵m²(250p²m³zx¹⁰)

1250 p²x¹²y³z⁶m⁵

Option 2: $\frac{x-12}{4}$ is the correct answer

Step-by-step explanation:

Given fraction is:

$\frac{2x-24}{8}$

In order to simplify, we can see that the function is already in compact form

So,

We can simplify the given fraction.

We can see that the numerator can be further simplified

$\frac{2(x-12)}{8}\\=\frac{x-12}{4}$

Hence,

Option 2: $\frac{x-12}{4}$ is the correct answer
