Question

please solve this sum by using factor method and divide it by the second number​

Answer 1

Step-by-step explanation:

x⁴+3x²-10 by x²+5

let x²=y

above given equation becomes

y²+3y-10 by y+5

= y²+(5-2)y-10/y+5

= y²+5y-2y-10/y+5

= y(y+5)-2(y+5)/y+5

=(y+5)(y-2)/y+5

on Canceling y+5 by y+5

= y-2

and y=x²

= x²-2

OR

(x-√2 )(x+√2 )
