Question

3x^2+4x-8=0 solve using Quadratic formula

Answer 1

x = (-2 ± 2√7) / 3

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

Answer 2

Answer: (-4+ 4√7)/6

Explanation:

3x^2+4x-8 =0

Using formula method

-b+
