<h3>I'll teach you how to solve 4x^2-25<0</h3>
-------------------------------------------------
4x^2-25<0
Add 25 to both sides:
4x^2-25+25 < 0+25
Simplify:
4x^2 < 25
Divide both sides by 4:
4x^2/4 < 25/4
Simplify:
x^2 < 25/4
whole sqrt -25/4 < x < whole sqrt 25/4
whole sqrt 25/4= 5/2
-5/2 < x < 5/2
Your Answer Is -5/2 < x < 5/2
plz mark me as brainliest if this helped :)
