Question

which polynomial is equivalent to4b^3(2b^4 - 10b^3 + 3)?A. 8b^7 - 40b^6 + 12b^3B. 8b^12 - 40b^9 + 12C. 8b^7 - 40b^6 + 12D. 8b^12 - 40b^9 + 12b^3

Answer 1

We are given the polynomial

`4b^3(2b^4-10b^3+3)`

To find the equivalent the polynomial

We will expand as follow

`4b^3*2b^4-4b^3*10b^3+4b^3*3`

We will obtain

`8b^7-40b^6+12b^3`

The answer is option A
