2(x -1) - 3(4 x² + 7 x +1)

(-16 x² +10 x - 3)  + (4 x² -29 x -2) these expressions are equivalent to the polynomial -12 r²- 19 r -5

Step-by-step explanation:

2(x -1) - 3(4 x² + 7 x +1)

= 2 x -2 -12 x² - 21 x - 3

 = -12 x² -19 x -5

This expression is equivalent to the polynomial -12 r² - 19 r -5

Another equation is

(-16 x² +10 x - 3)  + (4 x² -29 x -2)

 = -16 x² +10 x  - 3 + 4 x² - 29 x - 2

= -12 x² -19 x - 5

This expression is also equivalent to the polynomial -12 r² - 19 r -5
