The constant in an equation would be the number multiplied to x,
In the equation y - 6.7x, the constant would be 6.7
Notice how the top is an addition of two cubes, namely x and 2.
You can rewrite the equation as:

Now, (a + b)³ can be simplified down to (a + b)(a² - ab + b²)
Following the same pattern, we get:
