Question

The difference between the values of the polynomial 3x3 - 2x + 5 at x = 2
and x = 1 is​

Answer 1

Step-by-step explanation:

for x=2,

3×3 - 2×2 +5 =10

for x=1,

3×3 - 2×1 + 5 = 12

difference between them.

12-10=2

Answer 2

Step-by-step explanation:

p(x)=3×3-2x+5

p(2)=3×3-2(2)+5

=9-4+5=10

p(1)=3×3-2(1)+5

=9-2+5=12

Difference=12-10=2
