7 l 1 9 6 -65 -63
1 16 118 761 5264 (answer line)
So, x^3 + 16x^2 + 118x + 761 R5264
1 l 5 0 -18 3
5 5 -13 -10
So, 5x^2 + 5x - 13 R -10

1)(x^4+9x^3+6x^2-65x-63)/(x-7)or
]x^4+9x^3+6x^2-65x-63[x³ + 16x²+118x + 761
-(x⁴-7x³)
-----------
16x³+6x²
-(16x² -112x²)
----------------
118x² -65x
-(118x² -826x)
------------------
761x - 63
-( 761x - 5327)
-----------------------
5264
So the remainder is 5264
2.) (5x³-18x+3)/(x+1)
]5x³-18x+3[5x² -5x -13
-(5x³+5x²)
--------------
-5x²-18x
-(-5x² -5x)
---------------
-13x +3
-(-13x -13)
--------------
16
So 16 is the remainder
