Question

Transform the equation X3+3x2+x-4=0 into the equation whose roots are multiplied by 10.

Answer 1

Answer:

The given equation is

f(x)=x3+3x2−5x+1=0

Replace x by 2x in the above equation to get the desired equation.

The required equation is

f(2x)=(2x)3+3(2x)2−5(2x)+1=0

=8x3+43x2−25x+1=0

On solving the equation, we get

x3+6x2−20x+8=0
