Question

16x^2-25=0

Answer 1

x^2=16/25
so x=\[\left| 4/5 \right|\]
so x= 4/5 or x=-4/5 as on squaring both positive and negative we get positive

Answer 2

My teacher gave me -5/4, 5/4 as a answer

Answer 3

oh yeah it would be 5/4 and -5/4 as on taking 25 to other side we get x^2=25/16 and not 16/25

Answer 4

then you square root both sides?

Answer 5

yup
