Find the sum
(2x^2 + 5x - 7) + (3 - 4x^2 + 6x)
A. -2x^2 - 11x - 4
B. -2x^2 + 11x - 4
C. 2x^2 + 5x - 7
D. 2x^2 + 3x + 1
The sum of (2x^2 + 5x - 7) + (3 - 4x^2 + 6x) can be found by combining like terms:
(2x^2 + 5x - 7) + (3 - 4x^2 + 6x)
= 2x^2 + 5x - 7 + 3 - 4x^2 + 6x
= (2x^2 - 4x^2) + (5x + 6x) + (-7 + 3)
= -2x^2 + 11x - 4
Therefore, the sum is -2x^2 + 11x - 4.
The correct option is B. -2x^2 + 11x - 4.
