Question

Tyrone factored the polynomial completely. What is the value of B?

12x4+30x3+4x2+10x

Ax(Bx2+1)(2x+5)

Answer 1

b

Explanation:

Answer 2

B=3,A=2

Explanation:

We are given that a polynomial

`12x^4+30x^3+4x^2+10x`

We have to find the value of B.

Taking common 2x from the given polynomial

`2x(6x^3+15x^2+2x+5)`

`2x(3x^2(2x+5)+1(2x+5))`

Taking common factor
`(2x+5)` then we get

`2x(2x+5)(3x^2+1)`

After factorization compare with

`Ax (Bx^2+1)(2x+5)`

Then, we get

A=2,B=3
