Answer 1

Answer:

option 3 -14

Step-by-step explanation:

x=2 (given)

2x+5x^2-10=2(2)+5(2)^2-10

=4+5(4)-10

=4+20-10

=24-10

=14

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The value of the polynomial 2x + 5x² - 10 at x = 2 is

1. 12

2. 13

3. 14

4. 15

EVALUATION

Let p(x) be the given polynomial

Then p(x) = 2x + 5x² - 10

Putting x = 2 we get

p(2) = 2 × 2 + 5 × 2² - 10

⇒ p(2) = 4 + 20 - 10

⇒ p(2) = 14

FINAL ANSWER

Hence the correct option is 3. 14
