Question

Write the number of terms in each of the
following polynomials :
(i) 5x2 + 3x ax
(ii) ax +4-7
(iii) ax - by + y xz
(iv) 23 + axb: 2

STEP BY STEP EXPLANATION PLEASE ​

Answer 1

In algebra, terms are the values on which the mathematical operations take place in an expression. A term can be a constant or a variable or both in an expression.

 

In the expression, 3a + 8, 3a and 8 are terms.

Here is another example, 5x + 7 is the expression and 5x and 7 are the terms.

(1.)5x²+3×ax

= 5x²+3 ax

here, the no. of terms will be. 2 (5x² and 3ax)

(2.) ax÷4-7

= (ax/4)-7

here, the no. of terms will be. 2 (ax/4 and 7)

(3.)ax-by+y× z

=ax-by+yz

here , the no. of terms will be. 3 (ax,by and yz)

(4.)23+a×b÷2

= 23+ (ab/2)

here , the no. of terms will be. 2 (23 and ab/2)
