B can be eliminated, as 10x and 4x multiply to 40x^2, which is not in the expression.
The greatest common factor of all coefficients in the equation is 2. Divide all coefficients by 2 to get the following equation:
We will leave out this coefficient, 2, for now.
We'll need to find the factors of c:
c = -6
Factors of 6: {1,2,3,6}
The only factors in the answer choices that fit this are 2 and 3. D can be eliminated.
5x and 2x multiply to 10x^2. 5x and 2x also modify what b will equal. Use the answer choices A and C to find b:
A.
C.
Answer C comes up with the correct b value.
The answer is C. 2(5x - 2)(2x + 3).

See explanation below
Step-by-step explanation:
The zero matrix is the matrix which has m rows and n columns and all its elements are zero, for example:
This matrix has the property that, when applied to a vector, sends it to zero.
On the other hand, the multiplicative identity matrix is an square matrix that has 1's in its diagonal and zero's everywhere else.
This matrix has the property that when multiplied by another one, doesn't change the first matrix (leaves things the same way as they were, it's like multiplying by one)
For example, a 3 x 3 multiplicative identity matrix would be:
