If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -.
If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi.
If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible)
Hope I helped :)
Answer:
12x + y = 16
Step-by-step explanation:
Standard Form: Ax + By = C
Step 1: Write point-slope form
y + 4 = -12(x - 1)
Step 2: Find slope-intercept form
y + 4 = -12x + 12
y = -12x + 16
Step 3: Find standard form
12x + y = 16
Answer:
4x(2x - 1)
Step-by-step explanation:
8x² - 4x ← factor out 4x from each term
= 4x(2x - 1)
Answer: Our required answer will be
Step-by-step explanation:
Since we have given that
We need to get the difference:
1) We first open the second bracket and make appropriate change in signs :
2) Gather the like terms together :
Hence, our required answer will be
The answer is "Math".....but technically the official name for it is Mathematics.
