Find the product of the roots of the equation<br> xl-5x - 36 = 0

Marat540 [252]

Answer:

Step-by-step explanation:

Hello, I assume that you mean

$x^2-5x-36$

The product is -36.

$x_1 \text{ and } x_2 \text{ are the two roots, we can write}\\\\(x-x_1)(x-x_2)=x^2-(x_1+x_2)x+x_1\cdot x_2$

So in this example, it means that the sum is 5 and the product is -36.

Thank you

___

If two or three of the topping choices can be the same, then there are an additional ...

2(15C2) +15C1 = 2·105 +15 = 225

ways to make the pizza, for a total of ...

455 + 225 = 680

different types of pizza.

There is a factor of 2 attached to the number of choices of 2 toppings, because you can have double anchovies and tomato, or double tomato and anchovies, for example, when your choice of two toppings is anchovies and tomato.
