Question

Plssss hellpppp!!!!!
a) x²y-2xy+y=?
b) ax²+4ax+4a=?
c) 20x-60x²+45x³=?​

Answer 1

a).

`{x}^(2) y - 2xy + y = y( {x}^(2) - 2x + 1) \\ = y {(x - 1)}^(2)`

b).

`a {x}^(2) + 4ax + 4a = a( {x}^(2) + 4x + 4) \\ = a {(x + 2)}^(2)`

c).

`20x - 60 {x}^(2) + 45 {x}^(3) = 5x(4 - 12x + 9 {x}^(2) ) \\ = 5x {(3x - 2)}^(2)`

Answer 2

A. y(x-1)^2
B. a(x+2)^2
C. 5x(2-3x)^2
