[AI-generated answer — Bot GPT 3.5]

To subtract -7a^2+3a-9 from 5a^2-6a-4, we simply subtract the corresponding coefficients of like terms.

The subtraction of the first terms will give us 5a^2 - (-7a^2) = 5a^2 + 7a^2 = 12a^2

The subtraction of the second terms will give us -6a - 3a = -9a

The subtraction of the third terms will give us -4 - (-9) = -4 + 9 = 5

Putting it all together, the polynomial in standard form is 12a^2 - 9a + 5.
