Answer:
Here's the answer:
8x^2-230x+750=0
=>2(4x^2-115x+375)=0
=>(2x)^2 - 2 × 2x × 115/4 +(115/4)^2 - (115/4)^2 + 375=0
=>(2x-115/4)^2 - 13225/16 +375=0
=>(2x-115/4)^2 - 13225+6000/16=0
=>(2x-115/4)^2 -7225/16=0
=>(2x-115/4)^2=7225/16
=>2x-115/4=√7225/16
=>2x=85/4+115/4
=>2x=200/4
=>2x=50
=>x=25
Hope it helps :)
