Question

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

Answer 1

Answer:

9

Step-by-step explanation:

Given, p(x) = 5x² - 3x + 7

The value of p(x) at x = k is obtained by replacing all the x terms by k and simplifying.

==> p(1) = 5 - 3 + 7

==> p(1) = 9

Hence the required value is 9

Answer 2

for finding the value of the polynomial, p(x)=5x²-3x+7 at x=1​;

we need to substitute value of 'x' as '1'

p(x) = 5x²-3x+7

p(1)= 5($1^{2}$)-3 (1) +7 = 5-3+7 = 9.
