The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
Use BODMAS/BIDMAS/PEDMAS: 9 + 6(22 + 4) = 9 + 6(26) = 9 + 6 × 26 = 9 + 156 = 165
h= -4
x2 + 8x - 6 = 0 x2 + 8x + 16 = 22 (x + 4)2 = 22 x + 4 = ± √22 x = -4 ± √22
