I got -15 as the answer, hope it works
Sqrt of 56 is about 7.5
So 6 would be in the first blank and 8 would be in the second blank.
6,7,8 are consecutive
-0.6(-6.3)
When 2 numbers are side by side it is a multiplication problem.
Multiply -0.6 by (-6.3)
-0.6 x -6.3 = 3.78
The first one is 2x^2+2x-2
the second one is 2x^2-2x-2
the third one is 6h+6k
