a.) p(x)+q(x)
b.) p(x)-q(x)
c.) p(x).q(x)


tolong pakai cara urut, terimakasih!!​

Answer 1

Materi : Fungsi dan Relasi

p(x) = 2x - 4

q(x) = 3 - 5x

_________/

p(x) + q(x) = - 3x - 1

p(x) - q(x) = 2x - 4 - 3 + 5x = 7x - 7

p(x) . q(x) = ( 2x - 4 )( 3 - 5x ) = - 10x² + 26x - 12

Semoga bisa membantu
