Question

Write x^3- 7x + 7x^5 - 19 + x^2

in standard form.
A. -19 + 7x5 - 7x + x3 + x2
B. x3 – 7x + 7x5 – 19 + x2
0
C. 7x5 + x3 + x2 - 7x - 19
O D. -19 - 7x + x2 + x + 7x5

Answer 1

C

Explanation:

A polynomial in standard form is first term, variable with largest exponent followed by decreasing exponents to the last term, the constant

Given

x³ - 7x + 7
`x^(5)` - 19 + x² ← rearrange terms

= 7
`x^(5)` + x³ + x² - 7x - 19 ← in standard form → C
