I think this is correct, how it helps.
Answer:
x = 1/3 or x = -2/3
Step-by-step explanation:
Let's solve your equation step-by-step.
9x2+3x−2=0
For this equation: a=9, b=3, c=-2
9x2+3x+−2=0
Step 1: Use quadratic formula with a=9, b=3, c=-2.
x = 1/3 or x = -2/3
i believe the formula you need is; SA= n(3/10 ib) + 9b
