Question

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

Answer 1

Answer:

7

Step-by-step explanation:

if x = 2 in p(x) then

2×2-3×2+4

=4-6+4

=8-6+5

=2+5

=7

Answer 2

The required value = 7

Given :

The polynomial p(x) = 2x² - 3x + 5

To find :

The value of the polynomial for x = 2

Solution :

Step 1 of 2 :

Write down the given polynomial

Here the given polynomial is

p(x) = 2x² - 3x + 5

Step 2 of 2 :

Find the value of the polynomial for x = 2

Putting x = 2 in the polynomial p(x) we get

p(2) = ( 2 × 2² ) - ( 3 × 2 ) + 5

⇒ p(2) = 8 - 6 + 5

⇒ p(2) = 7

Hence the required value = 7
