Apolynomial function p(x) with rational coefficients has the given roots. find two additional roots of p(x)=0. i and 7 + 8i a) -1,1 b) -i, 7-8i c)-1, 56i d) no additional roots are possible also if anyone has the answers to the practice and the quick check i'm super behind and i need

B

Step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
