Question

in example : 1 , step 2 : x - 20x should be = -19x but the
answer u have written is -20x again so even the verification u have
done is wrong as your divident is coming 10
x 4 + 8 x
3 â€“ 7 x
2 + 79 rather it should be 10 x 4 + 8
x 3 â€“ 7
x 2 + x + 79 isn't it
???

In the mentioned query the polynomial is
10x4
+
8x3
â€“
7x2
+ 79 =
10x4
+
8x3
â€“
7x2
+ 0x + 79
It is not x, it is 0x = 0 Ã—
x = 0
Thus, 0x - 20x = 0 -20x =
-20x

in example : 1 , step 2 : x - 20x should be = -19x but the answer u have written is -20x again so even the verification u have done is wrong as your divident is coming 10 x 4 + 8 x 3 – 7 x 2 + 79 rather it should be 10 x 4 + 8 x 3 – 7 x 2 + x + 79 isn't it ???

in example : 1 , step 2 : x - 20x should be = -19x but the answer u have written is -20x again so even the verification u have done is wrong as your divident is coming 10 x ⁴ + 8 x ³ – 7 x ² + 79 rather it should be 10 x ⁴ + 8 x ³ – 7 x ² + x + 79 isn't it ???
