Ответ:
8x² + 4x - 10
Step-by-step explanation:
We will use the order of PEMDAS to solve
-> See attached
(6x+7) (3x-1) - (5x+3) (2x+1)
(6x+7) (3x-1) becomes 18x² - 6x + 21x - 7 which is equal too 18x² + 15x - 7
(5x+3) (2x+1) becomes 10x² + 6x + 5x + 3 which is equal too 10x² + 11x + 3
(18x² + 15x - 7) - (10x² + 11x + 3)
18x² - 10x² = 8x²
15x - 11x = 4x
-7 - 3 = -10
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
