Explanation:
If we are excluding the product being 0 then we can say that
Method 1
Through trial and error we can deduce that,
Method 2
Now we can identify our abc values and solve for x using the quadratic formula.
Through trial and error we can deduce that,
Explanation:
(A) if both
or
(B) if both
x is outside
The 1-D shaded x-axis illustrates this solution. The gap is out of bounds.
Explanation:
graph{(x+4)(x+6) > 0x^2 [-10, 10, -1, 1]}
And so,
and
x < -4 and x < -6 to x < -6#
Thus,
