What are the solutions to the quadratic equation (round to nearest hundredth) x2 + 6x
-6 = 0 ?

x = 0.88 OR x = -6.88

Step-by-step explanation:

Given the quadratic equation: + 6x - 6 = 0

Applying the quadratic formula to determine the solutions, we have:

x = (-b ± ) / 2a

where; a = 1, b = 6 and c = -6

x = ( -6 ± ) / 2

  = ( -6 ± ) / 2

  = (-6 ± ) / 2

x = (-6 ± 7.75) / 2

So that,

x = (-6 + 7.75) / 2 OR x = (-6 - 7.75) / 2

x = OR

x = 0.88 OR -6.88

Thus, the solutions are: x = 0.88 OR x = -6.88

ratio is 2 : 9

the answer is three

13.5 : 3
