Question

Multiply


(s+1/2)(s+1/5)

Answer 1

I got (2s+1)(5s+1)/10

Answer 2

s^2+7s/10+1/10

Answer 3

huh

Answer 4

is it only 1/2 and 1/5 or the whole expression being divided by 2 and 5

Answer 5

s+1/2 is in one () and s+1/5 is in the other ().

Answer 6

I mean is it [(s+1)/2][(s+1)/5

Answer 7

If I were to multiply this expression I would FOIL it, as in first, outer,inner, and last variables.
So (s+1/2)(s+1/5)=
you would multiply the first variables of each equation.
s*s=s^2
then you would multiply the outer variables of each equation
s*1/5=1/5s
Then the inner variables
s*1/2=1/2s
and finally the last variables
1/2*1/5=1/10
So your finished equation is
s^2+1/5s+1/2s+1/10
which can be simplified further into
(s^2)+(7/10s)+(1/10)

Answer 8

\[\left(s+\frac{1}{5}\right) \left(s+\frac{1}{2}\right)=s^2+\frac{7 s}{10}+\frac{1}{10}=\frac{1}{10} \left(10 s^2+7 s+1\right) \]
