How do you write a quadratic equation in standard form?
Lemur [1.5K]

Answer:

  • Powers of the variable descending left to right
  • right side of the equal sign is 0

Step-by-step explanation:

For some constants a, b, and c, the standard form* is ...

  ax^2 + bx + c = 0

___

It is nice if the leading coefficient (a) is positive, but that is not required.

The main ideas are that ...

  • Powers of the variable are descending
  • All of the non-zero terms are on the left side of the equal sign
  • Like terms are combined

_____

* This is the <em>standard form</em> for a quadratic. For other kinds of equations, when the expression is equal to zero, this would be called "general form."

dexar [7]

Answer:

1/6

Step-by-step explanation:

We can make a Punnett square to find number of favourable outcome

so

            cube1

         +

cube2    1          2          3        4          5         6

1            2         3           4        5          6        7      

2            3         4           5        6          7         8

6           7           8          9         10        11         12

The probability of rolling doubles given that the sum is 6

<h3> favourable outcome / number of outcome</h3>

 6 / 36

  1 / 6
