Question

find The value of m for which (y-1) is a factor of y 2 -m

Answer 1

$\small\bold{{\red{A}}{\blue{N}}{\red{S}}{\blue{W}}{\red{E}}{\blue{R}}{\red{❥}}}$

M is a number which when subtracted from the value of y 2 times makes y -1 its factor.

so , y-1=y2-m

=>y-1+m=y2

=>y-m=y2+1

=>y-m=y3

=>y-m/y=3

=>m=>3

applying to statement:-

Let y be 2

so, 2-1=2×2-3

=>1=1

hence is a factor of 1.

Hope it helped u buddy...

Thank you...☺❤

Answer 2

M is a number which when subtracted from the value of y 2 times makes y -1 its factor.

so , y-1=y2-m

so , y-1=y2-m=>y-1+m=y2

so , y-1=y2-m=>y-1+m=y2=>y-m=y2+1

so , y-1=y2-m=>y-1+m=y2=>y-m=y2+1=>y-m=y3

applying to statement:-

Let y be 2

so, 2-1=2×2-3

so, 2-1=2×2-3=>1=1

hence is a factor of 1.
