Question

( 7a-8b+2c) ও (2a+3b-d)

Answer 1

Step-by-step explanation:

Solve for d:

(7 a - 8 b + 2 c) (2 a + 3 b - d) = 0

Divide both sides by 7 a - 8 b + 2 c:

2 a + 3 b - d = 0

Subtract 2 a + 3 b from both sides:

-d = -2 a - 3 b

Multiply both sides by -1:

Answer: d = 2 a + 3 b

Answer 2

( 7a-8b+2c) + (2a+3b-d)

= 7a-8b+2c+2a+3b-d

= 7a+2a-8b+3b+2c+d

= 9a-5b+2c-d
