Question

If P(t) = t 3+ 2t 2+ t then find the values of P(3),P(-5) and P (2/5)​

Answer 1

Step-by-step explanation:

p(3) = 3×3+2×2×2+3

= 9+8+3

= 9+11

p(3)= 20

p(-5)= -5×3+2×(-5)×2+(-5)

= -15+(-20)-5

= -20-20

= -40

p(2/5) =2/5×3+2×2/5×2+2/5

= 17/5+12/5×2+2/5

= 17/5+22/5+2/5

= 17+22+2/5

= 41/5

p(2/5) = 8.2
