Question

In your notebook, set up the following addition using a vertical format and find the sum of the given polynomials. 3x2 2x - 5 and -4 7x2 10 x2 2 x - 9 - x2 9 x - 9 21 x2 2 x 20 10 x2 - 5 x - 1.

Answer 1

To add the polynomial equation, add or subtract the terms with same power of variable.

Thus addition of the given polynomial using a vertical format is,

$10x^2+2x-9$

Thus the option 1 is the correct option.

What is polynomial equation?

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

Here, n is any real number.

To add the polynomial equation, add or subtract the terms with same power of variable.

Given information-

The first polynomial equation in the problem is,

$3x^2 +2x - 5$

The second polynomial equation in the problem is,

$-4 +7x^2$

Rearrange the above equation as,

$7x^2-4$

To add in vertical format write down both the polynomial one below another.

The value of variable with same power should be write down the with same power of variable as,

$3x^2 +2x - 5\\7x^2 \;\;\;\;\;\;\;\;\;-4$

____________

$10x^2+2x-9$

_____________

Thus, addition of the given polynomial using a vertical format is,

$10x^2+2x-9$

Thus the option 1 is the correct option.
