how to solve many polynomial equations listed in a matrix?

I have a matrix where each row is a polynomial equation:

A=[0.01  620.085  -3750
   0.01  620.082  -3750
   0.01  620.079  -3750
   0.01  620.076  -3750];

I want to solve every row of matrix A. How can i do that, I tried:

for i=1:length(A)
I(i)=roots(A(i,:))';
end

I want to get the answer as follows:

I= [I(1,1) I(1,2)

I(2,1) I(2,2)

I(3,1) I(3,2)

I(4,1) I(4,2)];

Roots = arrayfun( @(x) roots( A( x, : ) ), 1 : 4, 'un', 0 );
[ Roots{ : } ].'

Thank you, it worked!

Here's a method withoutt loops,

[a,b,c]=deal(A(:,1),A(:,2),A(:3));

D=sqrt(b.^2-4.*a.*c);

I=[-b-D, -b+D]./(2.*a);

Thanks!
