Answer 1

Step-by-step explanation:

i)if the value of p is 2

then, -2(2)^3+2(2)^2+5(2)+8

= -2×8 + 2×4 + 10 + 8

= -16 + 8 + 18

= -16 + 26

= 10 ans

ii) if the value of p is -1

then, -2(-1)^3 + 2(-1)^2 + 5(-1) + 8

= -2×(-1) +2×1 + (-5) +8

= 2+2-5+8

= 4+3

= 7 answer

iii) if the value of p is 1/2

then, -2(1/2)^3 + 2(1/2)^2 + 5(1/2) +8

= -2×1/8 + 2×1/4 + 5×2/2×2 + 8×4/1×4

= -1+2+10+32/4

= -1+44/4

= 43/4

= 10.75 answer

this is your answers
