Can someone help me understand this I have a higher grade assignment and don’t understand thank you 12.5+4=7x+37

-2.928=x

Step-by-step explanation: 12.5+4=16.5

16.5=7x+37

16.5-37     37-37

-20.5=7x

divide 7 from both sides

x= -2.928

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."
