Question

solve the inequality
|2x+5|>|2-5x|​

Answer 1

Step-by-step explanation:

|2x+5|>|2-5x|

squaring on both sides we get

(4x^2 + 25 + 20x ) > (4+25x^2 - 20X)

40x +21 > 21x^2

21x^2 -40x - 21 < 0

21x^2 + 9x -49x -21 <0

3x(7x+ 3) -7( 7x + 3) < 0

(3x-7)(7x+3) < 0

so 3x-7 < 0 , x< 7/3

AND 7x+3<0 , x< -3/7
