Step-by-step explanation:
Hey mate
I have an interesting method to do this
if we want this method to be done
we could first calculate
(-b±√b²-4ac)/2a
Then we will get the roots of the equation
Then we could split the middle term easily
Here's the solution
First by doing with that formula
a=1 b=5 c=4
so in formula
(-5±√5²-4*1*4)/2*1
=(-5±√25-16)/2
=(-5±√9)/2
=(-5±3)/2
=(-5+3)/2 ,(-5-3)/2
=(-2/2),(-8/2)
=(-1),(-4)
So y=-1,-4
therfore
now we can add this value in split the middle term steps
y²+5y+4
y(y+1)+4(y-1)
(y+1)(y+4)
y=-1,-4
Done
;D
