Question

(y-1.5)(y-0.5)(y+0.5)(y+1.5)=24​

Answer 1

Answer:

(y-0.5)2 (y-1.5)2

Multiply and you will get the answer as 24

Answer 2

LHS

rearrange the terms

(y - 1.5)(y + 1.5)(y - 0.5)(y + 0.5)= 24

multiply both sides by 16

then

you get

16x^4- 40x^2 +9 = 384

let 4y^2 = t

then ,

t ^ 2 -10 t -375= 0

now solve it

you get yr answer
