Question

What are the solutions of the equation 3x^2+8x=12

Answer 1

Explanation:

3x² + 8x = 12

3x² + 8x - 12 = 0

a=3, b=8, and c=-12. Solving with quadratic formula:

x = [ -b ± √(b² - 4ac) ] / 2a

x = [ -8 ± √(8² - 4(3)(-12)) ] / 2(3)

x = (-8 ± √208) / 6

x = (-8 ± 4√13) / 6

x = -4/3 ± 2/3 √13

Answer 2

x= -4/3 + 2/3 square root of 13 or x= -4/3 + -2/3 square root of 13 !!
