Question

Find all possible real values of x, if 2 1 x-1 x+1 x+1 x x − + = 0.

Answer 1

Answer:

Cloth left with Tina = 20m 5cm - 4m 50cm

= (19m + 1m + 5cm) - (4m + 50cm)

= (19m + 100cm + 5cm) - (4m + 50cm)

= 19m + 105cm - 4m - 50cm

= 15m + 55cm

= 15m 55cm

Given:

Inequality

(x- (a -1)) (x - (a? +2))<0 holds for

To find:

The set of all possible real values of a

Solution:

Concept used:

(x-a) x - b) < 0 is true when a <x <

Consider,

(x-(a-1)) (x- (a* +2))<0

<x < a+2

a

But 1<x < 3

a-1=-1
