I'll teach you how to solve 4x^2-25<0

-------------------------------------------------

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 :)
