Solve -8k2 -12k plus 92

Answer 1

Presumably this is a quadratic equation in the form of -8k2-12+92 = 0 which will have two solutions.

First divide all terms by -4 to bring the equation at its lowest terms remembering that a - divided into a - is equal to a +

2k2+3k-23 = 0

Use the quadratic equation formula to factorise the equation:

(2k-5.446221994)(k+4.223110997) = 0

Therefore the solutions are: k = 2.723110997 or k = -4.223110997 to nine decimal places respectively.
