Question

If P(x) is equal to 2xcude - (x)sqr +3x +1 , then find the value of P(-1) + P(2)​

Answer 1

Answer:

14

Step-by-step explanation:

sub x=-1 in given eqn

then P(-1)=2*(-1)^3-(-1)^2+3(-1)+1=(-2-1-3+1)=-5

sub x=2 in given eqn

then P(2)=2*(2)^3-(2)^2+3*2+1=16-4+6+1=19

so P(-1)+P(2)=(-5)+19=14
