Answer:

4x² + 41x - 33

Step-by-step explanation:

  • F in foil stands for 'first'; take the first value in each bracket and multiply them together. So 4x × x = 4x²
  • O in foil stands for 'outside'; take the outermost values from each bracket and multiply them together. So 4x × 11 = 44x
  • I in foil stands for 'inside'; take the innermost values for each bracket and multiply them together. So -3 × x = -3x
  • Finally, L in foil stands for 'last'; take the last value in each bracket and multiply them together. So -3 × 11 = -33
  • Now, we can put this all together and simplify: 4x² + 44x - 3x - 33 → 4x² + 41x - 33.

Hope this helps!
