Answer:
A and D
Step-by-step explanation:
By finding the roots of all the equations, we see that options A and D are the only ones that require an imaginary number in order to solve
Answer:
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
