Expand this (3x-2/3y)^2

9x² - 4xy + y²

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

3x(3x - y ) - y(3x - y ) ← distribute both parenthesis

= 9x²- 2xy - 2xy + y² ← collect like terms

= 9x² - 4xy + y²

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
