Make the following expressions free from modulus sign :
(i) `|x^(2) -3x-4|` , (ii) `|x^(2)-7x+10|` if `x lt 5`

Text Solution

Verified by Experts

The correct Answer is:
(i) `{{:(-(x^(2)-3x-4)" ""if"" "x in (-1,4)),(x^(2)-3x-4" "if"" "x in (-oo,-1]uu[4,oo)):}`
\(ii) `{{:((x^(2)-7x+10)" "if" "xle2),(-(x^(2)-7x+10)" "if" "2ltxlt5):}`
