Question

Using the quadratic formula, Show all work to solve 3x2 − 5x − 2 = 0.
I am stuck

Answer 1

Answer:

X= 4/5

Step-by-step explanation:

3*2-5x-2=0

step 1 : combine/multiply like terms

6 - 5x - 2 = 0

6-2 -5x=0

4-5x=0

step 2: "separate" the x from the "normal" numbers (what happens on one side of the equation happens to the other side)

4 - 5x = 0

-4         -4

-5x = -4

step 3: divide by the coefficient of X

-5x / -5 = /4 / -5

x= 4/5

Answer 2

Answer:

x = 5 + i  ,  5 - i

       6          6

Step-by-step explanation:

x = -b ±√b∧2-4ac

             2a

x = -(-5) + $\sqrt{-5^2 - 4(3)(-2)}$

                 2(3)

= 5 + $\sqrt{-1}$

       6

= 5 - $\sqrt{-1}$

       6

hope this helps!
