What is the constant term in the polynomial expression -7x2 + 32x + 240, and what does it represent?

What's the factored form of that expression and what do the factors represent?

Given:

The polynomial expression [tex]-7x^2+32x+240[/tex].

To find:

The constant term in the polynomial expression and factored form.

Solution:

We have

[tex]-7x^2+32x+240[/tex]

Here, 240 is free from variable x. So, it is the constant term.

It represents the initial value of the expression, where x=0.

Using splitting the middle term, we get

[tex]-7x^2-28x+60x+240[/tex]

[tex]\Rightarrow -7x(x+4)+60(x+4)[/tex]

[tex]\Rightarrow  (x+4)(-7x+60)[/tex]

Therefore, the factored form is [tex](x+4)(-7x+60)[/tex].

It represents the two expressions, whose product is the given expression.
