The remaining solutions are -7 and 3.
Step-by-step explanation:
The synthetic division is shown in the attachment. After dividing the first two found factors from the polynomial, the remaining quadratic is ...
x^2 +4x -21 = 0
Its rational roots will be factors of -21, and the sum of their opposites will be 4. Knowing that 21 = 3·7, we can guess that the remaining roots are -7 and 3. The synthetic division confirms that. (A graph also confirms it.)

{x | x
Step-by-step explanation:
To solve this problem you must:
-Subtract 1.3 from both sides:
- Now, you must divide both sides of the inequality by -4.9, as you can see below (The direction of the sign changes):
The solution set is:
{x | x
The solution is x Step-by-step explanation:
See the solution in the attached figure
x
Step-by-step explanation:
given - 4.9x + 1.3 > 11.1 ( subtract 1.3 from both sides )
- 4.9x > 9.8 ( divide both sides by - 4.9 )
Remembering to reverse the direction of the inequality symbol as a result of dividing by a negative quantity.
x
solution set : x ∈ ( - ∞, - 2 )
1.3> 11.1 + 4.9x This way you never have to remember to turn the > into
Subtract 11.1 from both sides
-9.8 -9.8 / 4.9 -2
=−4.9x+0.0143
