(x-4)(3x^2-4x+3) it’s very urgent

3x^3 - 16x^2 + 19x - 12

Step-by-step explanation:

just multiply it out by multiplying every term in the 2nd parenthesis by every term in the first parenthesis.

3x^3 - 4x^2 + 3x - 12x^2 + 16x - 12

combine like terms

3x^3 - 16x^2 + 19x - 12

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
