Simplify 2x2(4x2 + 9x – 13)

Answer 1

\[2x^2(4x^2+9x-13)\]
\[2x^2(4x+13)(x-1)\]

Answer 2

6x4 + 18x3 – 26x2

8x4 + 18x3 – 26x2

8x2 + 18x – 26

6x2 + 18x – 26

this are my options

Answer 3

Oh.. Never mind my first comment then.
Expand 2x2(4x2 + 9x – 13)
\[2x^2*4x^2+2x^2*9x-2x^2*13=8x^4+18x^3-26x^2\]

Answer 4

so what do you do with that?

Answer 5

Look at the last part.
\[8x^4+18x^3-26x^2\]
That's the answer.
