Question

Simplify the expression. Use the variables, numbers, and symbols that are shown. Drag them to the appropriate box in the polynomial. Use standard polynomial format.

x(2x + 3) + (x - 3)(x - 4)

Answer 1

3x^2-4x+12! Hope this helps.

Answer 2

`3x^(2)-4x+12`

Explanation:

In this case we have to simplify the expression by giving it in the standard polynomial format, first we have to see what is the polynomial standard format, this is:

`ax^(2) +bx+c`

In the case of the expression presented we have to make the multiplications and additions to then organize the expression:

`x(2x+3)+(x+3)(x+4)`

First the multiplications:

`2x^(2) +3x+x^(2) -4x-3x+12`

Now the additions and organization:

`3x^(2)-4x+12`

Now we have the expression in the polynomial format.
