Mathematics

Assertion (A) : 5x + y2 - x3, xy + yz + zx, x2 - x + 1 are all trinomials.

Reason (R) : An algebraic expression which contains three different terms is called a trinomial.

  1. Both A and R are correct, and R is the correct explanation for A.

  2. Both A and R are correct, and R is not the correct explanation for A.

  3. A is true, but R is false.

  4. A is false, but R is true.

Answer

An algebraic expression which contains three different terms is called a trinomial.

So, reason (R) is true.

Given, 5x + y2 - x3, xy + yz + zx, x2 - x + 1

All three expressions have three distinct terms.

So, assertion (A) is true and, reason (R) is the correct explanation of assertion (A).

Hence, option 1 is the correct option.
