Question

Group all the unlike terms from among the given terms.
$-7x{y}^2,8x^2,9x^3,-100x,-11yx,20y^{2}x,96x,-7x^2,67xy,7x^4,3x^2,-11x^{2}y$.

• A. $-7x{y}^2,20y^{2}x,-11x^{2}y$
• B. $8x^2,-11yx,9x^3$
• C. $-11x^{2}y,67xy,7x^4$
• D. $9x^3,-11x^{2}y,7x^4$

Answer 1

The correct option is D $9x^3,-11x^{2}y,7x^4$

The terms given are,
$-7x{y}^2,8x^2,9x^3,-100x,-11yx,20y^{2}x,96x,-7x^2,67xy,7x^4,3x^2,-11x^{2}y$

Unlike terms are terms which contain the different variables or same variables but raised to different power.

$\therefore$ Among the given terms, $9x^3,-11x^{2}y,7x^4$ are unlike terms.
