What is the sum of the given polynomials in standard form? (x2 – 3x) (–2x2 5x – 3).
Rina8888 [55]

Sum of standard form polynomials means adding the terms of same variable. The sum of the given polynomial in standard form is,

-x^2+2x-3

<h3>What is polynomial equation?</h3>

A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.

Here, <em>n</em> is any real number.

In the polynomial equation the the terms are added or subtracted from each other only when the power of the variable is same.

Given information-

The first polynomial equations given in the problem is,

(x^2 - 3x)

The second polynomial equations given in the problem is,

(-2x^2+ 5x - 3).

To find the sum of these two polynomials, add the two terms together as,

(x^2 - 3x)+(-2x^2+ 5x - 3)

Let the result of the sum is f(x). Thus,

f(x)=(x^2 - 3x)+(-2x^2+ 5x - 3)\\f(x)=x^2-3x-2x^2+5x-3

Separate the similar power variable as,

f(x)=(x^2-2x^2)+(-3x+5x)-3\\f(x)=-x^2+2x-3

Thus the sum of the given polynomial in standard form is,

-x^2+2x-3
