Astudent performed row operations on a matrix as shown below.
n
(4 1214
o -1 3 1
3 2 4 5
0
an
[4 1 214
0 -1 3
3 0 107
which operations did the student perform?
2r2+r3 r3
2r3+-r3 → r3
2r2+r3 → r2 r3
2r2 r3

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
