Quadratic Formula:
-b +/- √b² - 4ac
x = --------------------------
2a
In your equation 3x² + 5x + 2 = 0:
a = 3
b = 5
c = 2
Now, plug in these values into the formula.
-5 +/- √5² - 4(3)(2) -5 +/- √25 - 4(6)
x = -------------------------------- ⇒ x = -----------------------------
2(3) 6
-5 +/- √25 -24 -5 +/- √1 -5 +/- 1
x = ------------------------ ⇒ x = --------------- ⇒ x = --------------
6 6 6
-5 +/- 1
Split x = ------------ into two solutions by solving it.
6
-5 + 1 -4
x = ------------ = ------
6 6
-5 - 1 -6
x = ----------- = ------ = -1
6 6
The two final solutions are x = -1 and x = -4/6
Answer:
it would be A and C
Step-by-step explanation:
I used photo math and it used C as its answer, but answer A simplifies to answer C therefore meaning they are both your answers! I hope this helped!
Answer:
38
Step-by-step explanation:
We are to solve for the expression;
2 + 3² × (5 - 1)
We should aply BODMAS here!
So starting with the brackets;
2 + 3² × 4
Then solving the multiplication part;
3² × 4 = 9 × 4 = 36
Finally adding the integers;
2 + 36 = 38
Uuuummm I think it’s a carrot?
