Which polynomial correctly combines the like terms and expresses the given polynomial in standard form? 9xy3 – 4y4 – 10x2y2 + x3y + 3x4 + 2x2y2 – 9y4

–13y4 + 3x4 – 8x2y2 + x3y + 9xy3
–13y4 + x3y – 8x2y2 + 9xy3 + 3x4
3x4 – 8x2y2 + x3y + 9xy3 – 13y4
3x4 + x3y – 8x2y2 + 9xy3 – 13y4

The standard form of a polynomial is the general way of writing the polynomial.

The standard form of the polynomial is (d)

The polynomial expression is given as:

Collect like terms

Evaluate the like terms

Rewrite the polynomial in decreasing order of the power of x

Hence, the standard form of the polynomial is (d)

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
