Question

Find the value of the polynomial p(x)=5x2
-3x+7 at x=1​

Answer 1

Answer:

9

Step-by-step explanation:

Here, p(x)=5x^2-3x+7

Where x=1

Therefore, p(x)=5*1^2-3*1+7

= 5*1-3+7

=5+4

=9

Answer 2

The value p(x) = 5x² - 3x + 7 at x = 1 is 9

Given :

The polynomial p(x) = 5x² - 3x + 7

To find :

The value of p(x) at x = 1

Solution :

Step 1 of 2 :

Write down the given polynomial

Here the given polynomial is

p(x) = 5x² - 3x + 7

Step 2 of 2 :

Find the value of the polynomial at x = 1

The value of p(x) at x = 1

= p(1)

= 5 × 1² - ( 3 × 1 ) + 7

= 5 - 3 + 7

= 9
