Question

first one to answer will b marked as brainliestttt!!!! Find the value of the polynomial ∶ 9x^2 − 3x + 9 at x = 1

Answer 1

$p(x) = 9 {x}^{2} - 3x + 9 \\ x = 1 \\ \\ p(1) = 9 {(1)}^{2} - 3(1) + 9 \\ \: \: \: \: \: \: \: \: \: = \: 9 - 3 + 9 \\ \: \: \: \: \: \: \: \: = 18 - 3 \\ \: \: \: \: \: \: \: \: \: = 15$
