m equals 4.815 (to 3 decimal places) & -5.815 (to 3 decimal places) for:

m2 + m - 28 = 0

If we substitute these values into the quadratic formula:

x = (-b + or - (b2 - 4ac)1/2) / 2a

then we have:

m = (-1 + or - (12 - (4 * 1 * -28))1/2) / (2 * 1)

m = (-1 + or - (1 - -112)1/2) / 2

m = (-1 + or - (1131/2)) / 2

m = -1 + or - 10.630 (to 3 decimal places) / 2

m = 4.815 (to 3 decimal places) & -5.815 (to 3 decimal places).

Q: What does 0 equals m2 plus m -28 equal?

That depends on the value you give to 'm'.

m = 49, so m2 would equal 98

No. they are parallel, since the slopes are both equal in this case 3. To be perpendicular the product of the slopes of both lines is equal to -1 (i.e., m1*m2 = -1).
