What is the dimension of the null space Null (A) of A = ​

the nullity of a matrix A is the demision of its null space:nullity A = dim (n(A).

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
