Test your understanding of this lesson Factor theorem and factorization using Factor theorem:-

1)
The factors of the polynomial P(x)=\(3x^2+5x-2\) are
  • (3x-1)(x-2)
  • (3x+1)(x+2)
  • (3x-1)(x+2)
  • (3x+1)(x-2)
2)
The factors of the cubic polynomial \(x^3-3x^2+142x-120\) are
  • (x-1)( x+10 )(x-12)
  • (x-1 )( x-10)( x-12 )
  • (x+1)( x-10)( x-12)
  • (x+1)( x+10)(x-12)
3)
If (y-2) is a factor of the polynomial \(y^5-ky^3-3y^4+2ky+4+3ky^2\) then the value of k is
  • \(\frac{3}{2}\)
  • -\(\frac{3}{2}\)
  • \(\frac{2}{3}\)
  • -\(\frac{2}{3}\)
4)
If \(x^3+px^2+qx+6\) has x-2 as a factor and leaves a remainder -39 when it is divided by x+3 then the values of p and q are
  • p=3, q=1
  • p=-3, q=1
  • p=3, q=-1
  • p=-3, q=-1
5)
If x+2m is a factor of \(x^5-4m^2x^3+2x+2m+3\) then m=
  • \(\frac{2}{3}\)
  • 1
  • -1
  • \(\frac{3}{2}\)
