Question

Write the following in standard form: 423_13x4 + 7x + 11x2-2. 0-13.24 + 4.3 + 11x2 + 7æ - 2 O 13.04 + 403 + 11x2 + 72 – 2 11x2 + 7x + 423 – 2 – 13.4 – 13.4 – 4.3 + 11x2 + 7x – 2 +

Answer 1

The standard form of any polynomial is

$ax^n+bx^{n-1}+cx^{n-2}+\cdots+d$

That means arranging the powers of the variable from greatest to smallest and putting the numerical term at last

The given polynomial is

$4x^3-13x^4+7x+11x^2-2$

The greatest power is x^4, then it should be the first term

The next term is with x^3

The next term is with x^2

The next term is with x

The numerical term at last

Then the standard form is

$-13x^4+4x^3+11x^2+7x-2$

The answer is A (first choice)
