The function V= √1.223w expresses the landing speed, V (in feet per second), as a function of gross weight, w (in pounds), of an
mylen [45]
<span>an equation that expresses the gross weight of an aircraft as a function of its landing speed will be given as follows:
</span><span> V= √1.223w
we make w the subject of the equation, we start by dividing both squaring both sides:
</span>V²=(√1.223w)²
V²=1.223w
next we divide both sides by 1.223 to get :
V²/1.223=1.223w/1.223
w=V²/1.223
hence the answer will be w=V²/1.223

The first few steps in deriving the quadratic formula are shown.
Kisachek [45]

In the first few steps for deriving the quadratic formula left side of the equation due to the distributive property for balancing the equation.

<h3>What is quadratic equation?</h3>

A quadratic equation is the equation in which the highest power of the variable is two.

Here, The first few steps in deriving the quadratic formula are shown in the table.

Use the substitution property of equality to solve it further,

-c=-ax² +bx

Now factor out the term a, to solve further as,

    - c = a (x² + b/a x)

for half of the b value and square it to determine the constant of the perfect square trinomial as,

     (b/2a)² = b²/4a²

Now  the distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation.

  -c + b²/4a² = a(x² + b/a x + b²/4a² )

Thus, the distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation.
