Question

Multiply 4x(8x^4-9x^2-4x)

Answer 1

The given expression is,

`4x(8x^4-9x^2-4x)`

Multiply using distributive property(A(B+C)=AB+AC),

`\begin{gathered} 4x*8x^4-4x*9x^2-4x*4x \\ =32x^(1+4)-36x^(1+2)-16x^(1+1) \\ =32x^5-36x^3-16x^2 \end{gathered}`

Therefore, the final expression is,

`32x^5-36x^3-16x^2`
