Synthetic division or polynomial division can not figure this out.

(2p^2+7p-39)/(2p-7)

The basic synthetic division algorithm only applies to quotients like this when the divisor (denominator) is a monic linear polynomial, meaning the coefficient of the leading term needs to be 1.

First write



Now, carry out the synthetic division:

...... | 2 .......  7  ...... -39
7/2  |    .......  7  ......  49
----------------------------
...... | 2 ...... 14  ......  10

So you have

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
