Question

If a,b,y are the zearos of polynomials x^3-6x^2-x+30 then ab +by+ya

Answer 1

Answer:

ab+by+ya=-1

Step-by-step explanation:

x³-6x²-x+30=0 comparing with ax³+bx²+cx+d=0

then a=1,b= -6,c= -1,d=30

question asked ab+by+ya=c/a we know that. ab+bc+ca=c/a so compare that with this...

substitute values

ab+by+ya= c/a => -1/1

hence ab+by+ya = -1
