Question

If 2|x| = \- 8| + |x + 8| then the complete set of
values of x are​

Answer 1

Step-by-step explanation:

Given x2−x+a−3<0

For at least one negative value of x.

The coefficient of x2 is positive. The expression on the left-hand side must be positive at infinitely many points. It can be negative at least one point if the smaller root were negative.

21−13−4a<0

⇒13−4a>1

⇒13−4a>1

⇒4a>12

⇒a<3

⇒a∈(−∞,3)
