Question

If p(x) = 5x² - 2x , then find the value of p(x) at x = 3 *​

Answer 1

Given ,

$x = 3.$

Solution ,

$p(x) = {5x}^{2} - 2x$

putting x = 3 ,

$p(3) = ({5 \times 3})^{2} - 2 \times 3 \\= {15}^{2} - 6 \\= 225 - 6 \\= 219.$

hopefully its helped u dear :)

Answer 2

Given ,

x = 3.

Solution ,

p(x) = 5x^2−2x

putting x = 3 ,

p(3) = (5×3) ^2−2×3

= 15^2−6

= 225−6

= 219.

hope it helps !
