Answer:
remainder =0
quotient=(y+1)
Step-by-step explanation:
p(y)=y²+6y+5
f(y)=y+5
by remainder theorem,
if x-a is divisor p(a)=remainder
therfore,
comparing (y+5) with X-a,
we get,
a=-5
p(-5)=remainder
=(-5)²+6*(-5)+5
=25-30+5
=0
let other factor be(y-a)
by factor theorem,
p(a)=0,
=>a²+6a+5=0
=>a²+a(5+1)+5=0
=>a²+5a+1a+5=0
=>a(a+5)+1(a+5)=0
=>(a+1)(a+5)=0
so, a=-1,a=-5;
factors are
(y+1)and(y+5)
