Answer:
1. (x - 3)^2
2. (2x - 1)^2
3. (3x + 2)^2
4. (2x + 4y)^2
5. (4a - 3b)^2
Step-by-step explanation:
1. x^2 - 6x + 9 =
(x - 3) (x - 3) = (x - 3)^2
x^2 - 3x - 3x + 9
x^2 - 6x + 9
2. 4x^2 - 4x + 1 =
(2x - 1) (2x -1) = (2x - 1)^2
4x^2 - 2x - 2x + 1
4x^2 - 4x + 1
3. 9x^2 + 12x + 4
(3x + 2) (3x + 2) = (3x + 2)^2
3x^2 + 6x + 6x + 4
3x^2 + 12x + 4
4. 4x^2 + 16xy + 16y^2
(2x + 4y) (2x + 4y) = (2x + 4y)^2
4x^2 + 8xy + 8xy + 16y^2
4x^2 + 16xy + 16y^2
5. 16a^2 - 24ab + 9b^2
(4a - 3b) (4a - 3b) = (4a - 3b)^2
16a^2 - 12ab - 12ab + 9b^2
16a^2 - 24ab + 9b^2
