Answer:

(4x² + 9x - 7) - (7x² + 5x - 1) = -3x² + 4x - 6

Step-by-step explanation:

(4x² + 9x - 7) - (7x² + 5x - 1)

Group like terms together.

(4x² - 7x²) + (9x - 5x) - (7 - 1)

Subtract 7x² from 4x².

-3x² + (9x - 5x) - (7 - 1)

Subtract 5x from 9x.

-3x² + 4x - (7 - 1)

Subtract 1 from 7.

-3x² + 4x - 6
