2.) 7a^2 + 50a + 7 = 7a^2 + a + 49a + 7 = a(7a + 1) + 7(7a + 1) = (a + 7)(7a + 1)
3.) 3x^2 + 11x - 20 = 3x^2 - 4x + 15x - 20 = x(3x - 4) + 5(3x - 4) = (x + 5)(3x - 4)
4.) x^2 + 7x - 18 = x^2 - 2x + 9x - 18 = x(x - 2) + 9(x - 2) = (x + 9)(x - 2)

The least number of computers that must be shipped is 10.
<h3>What is the least number of computers that must be shipped?</h3>
In order to determine the least number of computers that must be shipped, the equation that represents the cost of shipping should be equal to the selling price of the computers.
3000 + 100x = 400x
In order to determine the value of x, take the following steps:
3000 = 400x - 100x
3000 = 300x
x = 3000 / 300
x = 10
