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

$4b^3\times2b^4-4b^3\times10b^3+4b^3\times3$

We will obtain

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

The answer is option A
