50 POINTS!!! Plz show work questions are in the addon

1. Each term in this polynomial has a common factor of 3x^3:

12x^6-9x^4+18x^3=3x^3(4x^3-3x+6)

2. Not sure what the "vertical method" is, but I would guess it refers to some way of visualizing the distributive property.

(3x-5)(2x^2+7x-3)=3x(2x^2+7x-3)-5(2x^2+7x-3)

(3x-5)(2x^2+7x-3)=(6x^3+21x^2-9x)+(-10x^2-35x+15)

(3x-5)(2x^2+7x-3)=6x^3+11x^2-44x+15

3. You can use the same approach as in (2), or recall that (a+b)^2=a^2+2ab+b^2:

(5x-4y)^2=(5x)^2+2(5x)(-4y)+(-4y)^2

(5x-4y)^2=25x^2-40xy+16y^2

4. Recall that a difference of squares can be factored as a^2-b^2=(a-b)(a+b). So

(2x^2-7)(2x^2+7)=(2x^2)^2-7^2

(2x^2-7)(2x^2+7)=4x^4-49

Help 10 POINTS MATH IS NOT MY STRONG SUIT
Masja [62]

Answer:

infinite number of solutions

Step-by-step explanation:

Work with the second equation.  Subtract 8x from both sides.

- 4y + 8x - 8x = -8x - 12                   Collect like terms.

-4y = - 8x - 12                                   Divide by - 4

-4y/-4 = - 8x/-4 - 12/-4

y = 2x + 3

That is exactly the same line as the first given.  There is an infinite number of solutions.
