Please help me please !

(x - 2)

here's your solution

=> 8x^2 - 8x - 16

=> taking 8 as common from whole we get,

=> 8(x^2 - x - 2)

=> x^2 - x - 2

=>. now by middle term split ,

factorize this

=>. x^2 - 2x + x - 2

=> taking common from each term

=>. x(x - 2) + 1(x -2)

=> (x + 1) (x - 2)

=> hence your answer is

(x - 2)

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

f(x) has value 150 at x= 0

and 0 at x= 3

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