b) (4a - 7b) elevado a 2
c) (1/2a + 1/3b) elevado a 2
d) (1/3a^2 - 1/5b elevado a 2)elevado a 2
e) (3/2a +5/3b) elevado a 2

Answer 1

(2a+3b)²

(2a + 3b) . (2a + 3b)

4a² + 6ab + 6ab + 9b²

4a² + 12ab + 9b²

(4a-7b)²

(4a - 7b) . (4a -7b)

16a² - 28ab - 28ab + 49b²

16a² - 56ab + 49b²

(1/2a + 1/3b)²

(1/2a + 1/3b) . (1/2a + 1/3b)

1/4a² + 1/6ab + 1/6ab + 1/9b²

1/4a² + 2/6ab + 1/9b²

(1/3a² - 1/5b²)²

(1/3a² - 1/5b²) . (1/3a² - 1/5b²)

1/9a^4 - 1/15a²b² - 1/15a²b² + 1/25b^4

1/9a^4 - 2/15a²b² + 1/25b^4

(3/2a +5/3b)²

(3/2a + 5/3b) . (3/2a + 5/3b)

9/4a² + 15/6ab + 15/6ab + 25/9b²

9/4a² + 30/6ab + 25/9b²
