Answer 2

Answer:

x^2-7x+4

Step-by-step explanation:

4x^2 -3^2 is basically 4-3, leaving you with 1.

-3x-4x, you're adding to the negative value of -3x, giving -7x.

-4-(-8), a little tricky at first. a trick that i was taught is if you're subtracting a number with a negative number, treat it as if you're adding, therefore -4-(-8) = -4+8, giving you a positive 4.
