Question

If Polynomias Cate) is multiples
by (20² +59 +h) then the degreesh
the answery​

Answer 1

The polynomial (2a +3) is multiplied by (2a² + 5a + 3 ).

To find:

The degree of the answer.

Solution:

First let us multiply the given terms:

=(2a + 3)×(2a² + 5a + 3 )

= 2a(2a² + 5a + 3 ) + 3(2a² + 5a + 3 )

4 {a}^{3} + 10 {a}^{2} + 6a + 6 {a}^{2} + 15a + 64a

3

+10a

2

+6a+6a

2

+15a+6

4 {a}^{3} + 16 {a}^{2} + 21a + 64a

3

+16a

2

+21a+6

From the expression we can see that the degree of the polynomial is 3.

Therefore the degree of the answer that we receive on multiplying the given expressions is 3, thus the correct option is 4.
