Find intervals of an inequality
WebFirst step: Factor out the inequality. (what times what equals 15 and when added together makes 8?) (x+3) (x+5)<0 Step 2: Solve for x. This inequality has two answers. X can either be -3 or -5, since both, when plugged in for x, will make the inequality equal to zero.

Determine the critical points–the points where the rational expression will be zero or undefined. Step 3. Use the critical points to divide the number line into intervals. Step 4. Test a value in each interval.

WebThis inequality is asking me to find the interval(s) on which a positive quadratic (which graphs as a right-side up parabola) is negative (that is, is below the x-axis). That's easy: picturing the parabola in my head, I see that the solution will be the interval between the two zeroes. So all I have to do is find the zeroes and pick the ...
