Multiply the ones digit of the bottom number to the next digit to the left in the top number. Find the zeros of an equation using this calculator. This happens when the algebraic multiplicity of at least one eigenvalue λ is greater than its geometric multiplicity (the nullity of the matrix, or the dimension of its nullspace). What is the algebraic multiplicity of this eigenvalue? 2. This polynomial is considered to have two roots, both equal to 3. Ax=x for each . Algebraic multiplicity of is the multiplicity of in the characteristic polynomial det(A xI), i.e. .
