Question

2) Find the value of polynomial p(x) = 2x 3 - 3x + 5 for x = 2 and x = 0​

Answer 1

Solution: Polynomial p(x)=2×2-3+5

Put x =2 In the given Polynomial

$\therefore \bold{p(2) = 2 \times 22 - 3 \times 2 + 5}$

$\bold{2 \times 4 - 6 + 5}$

$\bold{ = 8 - 6 + 5}$

$\therefore \bold{p(2) = 7}$

Answer 2

Answer:

Solution: Polynomial p(x)=2×2-3+5

Put x =2 In the given Polynomial

\therefore \bold{p(2) = 2 \times 22 - 3 \times 2 + 5}∴p(2)=2×22−3×2+5

\bold{2 \times 4 - 6 + 5}2×4−6+5

\bold{ = 8 - 6 + 5}=8−6+5

\therefore \bold{p(2) = 7}∴p(2)=7
