If a -4x2 plus 3x-4 and B -5x2 -4x plus 3?

Answer 1

To compare the two polynomials A and B, we first express them clearly: A = -4x² + 3x - 4 and B = -5x² - 4x + 3. The leading coefficient of A is -4 and for B it is -5, indicating that both are downward-opening parabolas, but B opens more steeply due to its larger negative coefficient. By examining the coefficients and constants, we can see that A has a higher value for x² terms, while B has a greater negative impact from its linear and constant terms. Thus, A generally will have higher values than B for larger positive x and lower values for larger negative x.
