Question

(8c-9b)(x-5a)+(3x+3c)(6a-2b)

Answer 1

8cx + 45ab + 18ax - 2bc - 15bx - 22ac

Explanation:

• (8c - 9b)(x - 5a) + (3x + 3c)(6a - 2b)
• 8cx - 9bx - 40ac + 45ab + 18ax + 18ac - 6bx - 2bc
• 8cx + 45ab + 18ax - 2bc - 15bx - 22ac

Answer 2

8cx - 22ac - 15bx + 45ab +18ax - 6bc.

Explanation:

(8c-9b)(x-5a)+(3x+3c)(6a-2b)

= 8c (x-5a) -9b(x-5a) + 3x(6a-2b) + 3c(6a-2b)

= 8cx - 40ac -9bx + 45ab + 18ax - 6bx + 18ac - 6bc

Combining like terms:

= 8cx - 22ac - 15bx + 45ab +18ax - 6bc.
