good job

anonymous · Answer

no thats the polynomial for the question

8x^2+24x+16 

= 4(2x^2 + 6x + 4)
= 4(2x +2)(x + 2)

campbell_st · Answer

an easy method is to use the factor theorem 

if 

x -2 is a factor   then x = 2 is a zero

so find 

P(2) BY substituting x = 2 into the polynomial 

if P(2) = 0.... then x - 2 is a factor

repeat the process for the other factors... 

and it saves trying to factor or solve the quadratic...

campbell_st · Answer

so 

$$P(2) = 8(2)^2 + 24(2) + 16$$
