Answer 2

Answer:

$p(x) = {kx}^{2} + 10x - 2 \\ p(1) = k + 10 - 2 = 3 \\ \: \: \: \: \: \: \: \: \: =k + 8 = 3 \\ \: \: \: \: \: \: \: \: \: = k = - 5 \\ p( - 1) = ( - 5)( - 1^{2} ) + ( - 10) - 2 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = - 5 - 10 - 2 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = - 17$
