This is a difference of squares pattern which factors to a Sum & Difference:  49h^2-16, which factors to (7h+4)(7h-4)

Hello Kayla,

It looks like Lindsey copied the wrong question.  As for the inequality above, I would divide both sides by 4 vs. distributing the 4...it will save you time and reduce your chances for errors...than subtract 1 from both sides with the last step being divide both sides by 5...which will result in y > -2 

Multiply both sides by the denominator, which will leave us with the numerator >= to zero, than look at the critical point that make the numerator go to zero, namely 0, -9 , and 6.  Next test points to the right and left of these values to see if it makes the inequality true...remember x cannot equal -5, or +2 because of the denominator. Start testing regions between these critical points to locate the solution regions.

Its a Sum of Cubes pattern:  (a+b)(a²-ab+b²)....First factor out the "9" ... 9(x+2)(x²-2x+4)

Use Synthetic Division:   

-7 | 4   34   39         4    (34-28)    (39-42)    =    4X + 6 - 3/(x+7)
