what are the two characteristics we look for when trying to solve a quadratic equation?


A. A positive coefficient for x^2 & the equation set equal to 0


B. Factor and cancel


C. Distribute like terms


D. There is no such thing as a quadratic equation

Answers

Answer 1

Answer:

Answer A makes the most sense by far.  

Step-by-step explanation:

Answer A makes the most sense by far.   However, strictly speaking, the coefficient of x^2 does not have to be positive if we're using the quadratic formula.  Using some other approach, such as factoring, obtaining a positive coefficient for x^2 is helpful.

90 minus 50 divided by 5 times 6 plus 2

Answers

Anwer:32

Step-by-step explanation:

Answer:

32

Step-by-step explanation:

To find out what to do first, use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, ans Subtraction)

Now it should look like this: (90-((50/5)*6)) + 2

First, divide 50 by 5 and get 10

So now it will be like this: (90-(10 x 6) + 2

Next, multiply 10 by 6 and you'll get 60.

The problem is looks like this: (90 - 60) + 2

Then, subtract 60 from 90 and get 30.

30 + 2

Lastly, add 30 and 2 to get 30.

Hope this helps.
