Question

Anyone know the answer?? ​

Answer 1

the second option

Explanation:

in ax²+bx+c = 0:

`x = (-b+-√(b^2-4ac) )/(2a)`

subtract both sides by 6 to get to this form, as the right side will be left with 0

6x² + 8x - 6 = 0

here, the coefficient for x² (a) is 6, the coefficient for x (b) is 8, and the remaining number added on (c) is -6

plugging our numbers into the formula, we get

`x = (-8+-√((-8)^2-4(6)(-6)) )/(2(6))\\= (-8+-√(64-(-144)) )/(12) \\= (-8+-√(208) )/(12) \\ = (-8+√(208) )/(12) or (-8-√(208) )/(12)\\= 0.53518375848 or -1.86851709182\\= approximately -1.87, 0.54`
