Answer:

Part 1) Option C x^{2}-4

Part 2) Option A (x+6)(x-6)

Part 3) Option C (2x+9)(2x-9)

Part 4) Option C Prime

Part 5) Option C 2(x+3)(x-3)

Part 6) Option A 3(x^{2} -7)

Step-by-step explanation:

we know that

A difference of square can be factored in the form

a^{2}-b^{2}=(a+b)(a-b)

Part 1) Find the product: (x + 2)( x - 2)

Applying difference of square

(x + 2)( x - 2)=x^{2}-2^{2}

(x + 2)( x - 2)=x^{2}-4

Part 2) Factor Completely: x^{2} -36

Applying difference of square

x^{2} -36=(x+6)(x-6)

Part 3) Factor Completely: 4x^{2} -81

Applying difference of square

4x^{2} -81=(2x+9)(2x-9)

Part 4) Factor Completely: x^{2} +16

Is not a difference of square

Is prime

therefore

Is not possible to factored

Part 5) Factor Completely: 2x^{2} -18

2x^{2} -18=2(x^{2} -9)

Applying difference of square

2(x^{2} -9)=2(x+3)(x-3)

Part 6) Factor Completely: 3x^{2} -21

Is not a difference of square

3x^{2} -21=3(x^{2} -7)

2. Solve this equation for x:<br> 0.17k - 0.43 = 0.25k + 0.05
stepan [7]

Answer:

k = 6

Step-by-step explanation:

im guessing you meant solve for k

0.17k - 0.43 = 0.25k + 0.05

-0.17k             -0.17k

-0.43 = 0.08k + 0.05

-0.05               -0.05

-0.48 = 0.08k

divide both sides of the equal sign by 0.08

6 = k
