Answer:

9x² - 12x + 4

Division Property

Step-by-step explanation:

(3x-2)² = (3x-2)(3x-2)

using the foil method we get:

9x² - 6x - 6x + 4

combine 'like' terms to get:

9x² - 12x + 4

2x = 10  To get 'x' by itself, since it's being multiplied by 2 we must do the inverse operation which is division

If we divide one side of an equation by 2 we must do the same to the other side, giving us:

x = 10/2 which is x = 5

Answer:

Question 5 :

[tex]9x^{2} - 12x + 4[/tex]

Question 6 :

Division property: divide both sides by 2

Step-by-step explanation:

Question 5 :

[tex](3x - 2) ^{2} [/tex]

[tex](3x - 2)(3x - 2)[/tex]

[tex]3x(3x−2)−2(3x−2)[/tex]

[tex]3x(3x)+3x(−2)−2(3x−2)[/tex]

[tex] {9x}^{2} - 6x - 6x + 4[/tex]

[tex]9x^{2} - 12x + 4[/tex]

Question 6 :

[tex]2x = 10[/tex]

[tex] \frac{2x}{2} = \frac{10}{2} [/tex]

[tex]x = \frac{10}{2} [/tex]

[tex]x = 5[/tex]

Hope it is helpful....
