Answer: (-4+ 4√7)/6
Step-by-step explanation:
3x^2+4x-8 =0
Using formula method
-b+
Answer:
x = (-2 ± 2√7) / 3
Step-by-step explanation:
x = [ -b ± √(b² − 4ac) ] / 2a
Here, a = 3, b = 4, and c = -8.
x = [ -4 ± √(4² − 4(3)(-8)) ] / 2(3)
x = [ -4 ± √(16 + 96) ] / 6
x = (-4 ± √112) / 6
x = (-4 ± 4√7) / 6
x = (-2 ± 2√7) / 3
