You can definitely multiply 2x2 matrices with each other. In fact you can multiply a AxB matrix with a BxC matrix, where A, B, and C are natural numbers. That is, the number of columns of the first matrix must equal the number of rows of the second matrix--we call this "inner dimensions must match."

How would you factor 2x squared - 72?
2x2 - 72 would be factored into (2x - 12)(x + 6) or (2x + 12)(x - 6) To double check, multiply each pair: (2x - 12)(x + 6) = 2x2 + 12x - 12x - 72 = 2x2 - 72 (2x + 12)(x - 6) = 2x2 - 12x + 12 x - 72 = 2x2 - 72

How can a system of linear equations be represented as a matrix equations?
Here is a simple way to see it that will help you both understand and remember. Take two equations in two unknowns. You can generalize later. Make a 2x2 matrix using the coefficients only. Now if you multiply this equation by the vector (x,Y) written as a column and placed on the right side of the matrix and you have the 2 equations you started with. Now put the constants, that is to say what each equation is equal to, on the right side of the = sign. If you invert the coefficient matrix on the left, the 2x2 one, and multiply both sides by that inverse, the equation is solved. There is another method known as Cramer's rule that can help you to solve equations using matrices. I suggest you look that one up if you are interested or ask for some more help!
How can I multiply two 2x2 matrices?
To multiply two 2x2 matrices, you need to multiply corresponding elements in each row of the first matrix with each column of the second matrix, and then add the products. The resulting matrix will also be a 2x2 matrix.
Do you multiply matrices?
I do not. I f*cking hate matrices. I multiply sheep.
Is the set of all 2x2 invertible matrices a subspace of all 2x2 matrices?
I assume since you're asking if 2x2 invertible matrices are a "subspace" that you are considering the set of all 2x2 matrices as a vector space (which it certainly is). In order for the set of 2x2 invertible matrices to be a subspace of the set of all 2x2 matrices, it must be closed under addition and scalar multiplication. A 2x2 matrix is invertible if and only if its determinant is nonzero. When multiplied by a scalar (let's call it c), the determinant of a 2x2 matrix will be multiplied by c^2 since the determinant is linear in each row (two rows -> two factors of c). If the determinant was nonzero to begin with c^2 times the determinant will be nonzero, so an invertible matrix multiplied by a scalar will remain invertible. Therefore the set of all 2x2 invertible matrices is closed under scalar multiplication. However, this set is not closed under addition. Consider the matrices {[1 0], [0 1]} and {[-1 0], [0 -1]}. Both are invertible (in this case, they are both their own inverses). However, their sum is {[0 0], [0 0]}, which is not invertible because its determinant is 0. In conclusion, the set of invertible 2x2 matrices is not a subspace of the set of all 2x2 matrices because it is not closed under addition.
Multiplication of 2x2 matrices is commutative?
No. Multiplication of matrices is, in general, non-commutative, due to the way multiplication is defined.

What is the significance of Pauli matrices in quantum mechanics?
Pauli matrices are a set of three 2x2 matrices that are crucial in quantum mechanics for representing the spin of particles. They are used to describe the intrinsic angular momentum of particles, which is a fundamental property in quantum mechanics. The Pauli matrices are also important in the context of quantum computing and in understanding the behavior of quantum systems.
What is inverse of 2x2 matrix A can you find the inverse of any given matrix?
The inverse of a 2x2 matrix:[a b][c d]is given by__1___[d -b]ad - bc [-c a]ad - bc is the determinant of the matrix; if this is 0 the matrix has no inverse.The inverse of a 2x2 matrix is also a 2x2 matrix.The browser used here is not really suitable to give details of the inverse of a general matrix.Non-singular square matrices have inverses and they can always be found. Singular, or non-square matrices do not have a proper inverses but canonical inverses for these do exist.
