answer

Explanation:

Step1: Write the subtraction expression

$$(-5x^2 - 7x + 2) - (-5x^2 + 7x + 2)$$

Step2: Distribute the negative sign

$$-5x^2 - 7x + 2 + 5x^2 - 7x - 2$$

Step3: Combine like terms (x² terms)

$$(-5x^2 + 5x^2) + (-7x -7x) + (2 - 2)$$

Step4: Simplify each term group

$$0 -14x + 0 = -14x$$
