Answer 1

A. (roq)(x)=2(-3x+4)^2+3(-3x+4)+5
=2(9x^2-24x+16)+3(-3x+4)+5
=18x^2-48x+32-9x+12+5
=18x^2-57x+49

B. (qor)(x)=-3(2x^2+3x+5)+4
=-6x^2-9x+15+4
=-6x^2-9x+19

C. (roq)(1)= 18x^2-57x+49
=18(1)^2-57(1)+49
=67-57
=10

D. (qor)(-5)=-6x^2-9x+19
=-6(-5)^2-9(-5)+19
=150+45+19
=214

kalau membantu .. jdikan jawabanku jawaban terbaik yaa
