Answer:
Box 1 = -4
Box 2 = -3
Box 3 = -5
Step-by-step explanation:
-4[tex]x^{2}[/tex] + 2x - 5(1 + x)
=> -4[tex]x^{2}[/tex] + 2x - 5 - 5x
=> -4[tex]x^{2}[/tex] + (2x + - 5x) -5
=> -4[tex]x^{2}[/tex] - 3x - 5
This equation can no more be divided / simplified, so,
The answer = -4[tex]x^{2}[/tex] - 3x - 5
So, in the boxes, the answer will be,
Box 1 = -4
Box 2 = -3
Box 3 = -5
