Solve the following questions: a. (b + c) (d - e) b. (3b - 4) b c. (2a + 4a) d. b (2 - 4b) e. (4b - 2a) (2...

1. Solve the following questions:
a. (b + c) (d - e)
b. (3b - 4) b
c. (2a + 4a)
d. b (2 - 4b)
e. (4b - 2a) (2 - 5)
f. 2d (a - 2b)
g. a - 3b
h. 6 (2e + f)
i. 6 (3f - 4e)
2. a (b + c) = e => at b x t b x t = e
c x d = e => at b d = b t d = c e
3. a (2a + 4a) - b (3b - 4b)
=> 2a^2 + 4a^2 = 3b^2 + 4b^2 - b^2 = 2

Answer

  1. a. (b + c) (d - e) = bd - be + cd - ce

    b. (3b - 4) b = 3b^2 - 4b

    c. (2a + 4a) = 6a

    d. b (2 - 4b) = 2b - 4b^2

    e. (4b - 2a) (2 - 5) = 4b(2 - 5) - 2a(2 - 5) = 8b - 20b - 4a + 10a = -12b + 6a

    f. 2d (a - 2b) = 2da - 4db

    g. a - 3b

    h. 6 (2e + f) = 12e + 6f

    i. 6 (3f - 4e) = 18f - 24e

  2. The equations given seem to be transformations or identities. Without additional context, they cannot be solved further.

  3. a (2a + 4a) - b (3b - 4b) = 6a^2 - 3b^2
