Division → Multiplication → Addition → Subtraction
- B stand bracket
- O stand of
- D stand division
- M stand Multiplication
- A stand for addition
- S stand for subtraction
The quadratic formula is:
(-b ± √b² - 4ac)/2a
So first we need to find what a, b, and c are by making the equation equal to 0.
We can do this by adding 13x and subtracting 10 to get -7x² + 13x - 10, so your values would be a = -7, b = 13, and c = -10.
Now you can just substitute them into the equation:
(-13 ± √13² - 4 × -7 × -10)/-14
I believe that is your answer in standard form, so I hope this helps!
Option one for the first question would be best because it is 2500 greater. Option 1 is 80000 while option 2 is only 77500.
Answer:
The answer is x = -7.7 ans x = -1.3
