Answer:
74.32
Step-by-step explanation:
1,858 divided by 25= 74.32
Well in order to get a factor you have to set the 2 x seperat and the last number too.. this will give you (x )(x ) they are both negative so one sign has to be a positive and the other a negative, lets find out what can we seperate the last term to, well lets see what numbers multiplied that give you -16 when adding or subtracting it gives you -6
E.J. 4 times -4 is 16 but when adding or subtracting it give you 0
lets try this 8 and 2 wehn multiplied it gives you 16 and when adding or subtracting it gives you eitehr 10 or 6!! Wow 6 that is what you need in order to get the factors of the trinomial.... SO now our factors look like (x 2)(x 8), our last step is to find out where the signs go, well if we know that the 6 is negative then we want to make our largest number a negative, this means 8 is negative so 2 will be positive so our factors now are (x+2)(x-8)... now which of these are in your choices?? well only the (x+2) so your second option would be the answer...
Hope this helps
The problem statement gives the correct answers for parts (a) and (b). The total number of roots of the characteristic polynomial is the dimension of the matrix: 6. The eigenvalues are the zeros of the characteristic polynomial, 3 (multiplicity 2), 6 (multiplicity 3), and -1.
(c) The matrix is not invertible when one or more eigenvalues is zero. None of yours are zero, so the matrix is invertible.
