Answer on Trigonometry Question for Kristen Woods

Question #22412
Solve the given equation.

12a. |9x-4|=20

12b. |2x^2-x-1|=-5
Expert's answer
12a. |9x-4|=20

Consider two cases:

x = 24/9 = 8/3


x = -16/9

So we have two solutions:
-16/9 and 8/3


12b. |2x^2-x-1|=-5

This equation has no solutions since the left hand sideis always non-negative:
while the righthand side is negative
-5 < 0
and therefore they are nonequal for all values of x.
