Answer:

Explanation:

1.
f(5) = 5(5^2) - 4(5) + 1
= 125 - 20 + 1
= 106

2. (g + h)(x) = (3x - 2) + (x + 1)
= 3x - 2 + x + 1
= 4x - 1

3. f(1) - h(1) = [5(1^2) - 4(1) + 1] - [(1) + 1]
= (5 - 4 + 1) - (2)
= 2 - 2
= 0

<h2>Perfect Squares</h2>

Perfect square formula/rules:

$a^2+2ab+b^2=(a+b)^2$
$a^2-2ab+b^2=(a-b)^2$

Trinomials are often organized like $ax^2+bx+c$ .

The <em>b</em> value in this case is <em>c</em>, and it will always equal the square of half of the <em>b</em> value.

Perfect square trinomial: $ax^2+bx+(\dfrac{b}{2})^2$
or $ax^2-bx+(\dfrac{b}{2})^2$

<h2>Solving the Question</h2>

We're given:

$c^2-4c$

In a trinomial, we're given the $ax^2$ and $bx$ values. <em>a</em> in this case is 1 and <em>b</em> in this case is 4. To find the third value by dividing 4 by 2 and squaring the quotient:
