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

Answer:

$3x^{2}-4x+12$

Step-by-step 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.
