Question

24x^2-146x+221
tell the value of x....​

Answer 1

Step-by-step explanation:

When x < 17/6 i.e.) 1: f(1) = 24 - 146 + 221 = 99 > 0 --> True

When 17/6 < x < 3.25 i.e.) 3: f(3) = 24(9) - 146(3) + 221 = -1 < 0 --> False

When x > 3.25 i.e.) 4: f(4) = 24(16) - 146(4) + 221 = 21 > 0 --> True

--> Solution: x < 17/6, x > 3.25
