Question

In the polynomial a(x) = 40 x – x² find a(10) and a(30)​

Answer 1

Answer:

300 , 300

Step-by-step explanation:

a(10) = 40(10) - 10(10) = 30(10) = 300

a(30) = 40(30) - 30(30) = 10(30) = 300

Answer 2

Given Question -: In the polynomial a(x) = 40 x – x² find a(10) and a(30)

let's try to solve the question

we have

$a(x) = 40x - {x}^{2}$

so

$a(10) = 40 \times 10 - {40}^{2}$

$a(10) = 400 - 1600$

$a(10) = - 1200$

Also

$a(30) = 40 \times 30 - {30}^{2}$

$a(30) = 1200 - 900$

$a(30) = 300$

Hope this will help you..
