M-N is $M-N=2x^2+11x-9$

Option B is correct.

Step-by-step explanation:

If $M=5x^2+7x-4$ and $N=3x^2-4x+5$ then find M-N

We need to subtract N from M

We will combine like terms (terms having same variable and exponent) and then solve them:

$M=5x^2+7x-4$

$N=3x^2-4x+5$

$M-N=5x^2+7x-4-(3x^2-4x+5)\\M-N=5x^2+7x-4-3x^2+4x-5\\Combining\,\,like\,\,terms:\\M-N=5x^2-3x^2+7x+4x-4-5\\M-N=2x^2+11x-9$

So, M-N is $M-N=2x^2+11x-9$

Option B is correct.
