Q3 of 84 Page 55

Write the following polynomials in standard form.

i. 4x2 + 7x4 - x3 – x - 9


ii. p + 2p3 + 10p2 + 5p4 – 8

i. In standard form the terms are arranged from highest power of the variable to the lowest power.

So the standard form is as follows:


7x4 – x3 + 4x2 – x + 9.


ii. In standard form the terms are arranged from highest power of the variable to the lowest power.


So the standard form is as follows:


5p4 + 2p3 + 10p2 + p – 8.
