To simplify the expression (9x26x+2)(x2+4x39), we need to distribute the negative sign across the second polynomial and then combine like terms. Here’s the step-by-step solution:

  1. Rewrite the expression: 9x26x+2(x2+4x39)

  2. Distribute the negative sign: 9x26x+2x24x+39

  3. Combine like terms:

    • For the x2 terms: 9x2x2=8x2
    • For the x terms: 6x4x=10x
    • For the constant terms: 2+39=41
  4. Putting it all together, we get: 8x210x+41

So, the simplified expression is: 8x210x+41
