Question

Find the value of polynomial p(x) =2x2-3x+5 for x=2.

Answer 1

Answer:

$p(2) = 2 \times 22 - 3 \times 2 + 5 \\ = 2 \times 4 - 6 + 5 \\ = 8 - 6 + 5 \\ { } \ \\ p(2) = 7$

Answer 2

As per question we have given p(x) = 2×2-3x+5

& x=2.

so put value of x in p(x) and solve

so u get result i.e., equal to 3.
