# 1

x^2+2x+4 can be written as

x^2 + x(2) + 4*1^2

I think that the best choice would be

1 big square, 1 tall rectangle, 4 little squares

# 2

–3f^2 + 4f – 3 + 8f^2 + 7f + 1

just collect terms of the same power

(-3+8)f^2 + (4+7)f + (-3+1)

5f^2 + 11f – 2

# 3

(2x^2 + 6x + 1) + (–7x^2 + 2x – 3)

(2-7)x^2 + (6+2)x + (1-3)

-5x^2 + 8x – 2

# 4

(3x^2 – 7x – 4) – (6x^2 – 6x + 1)

(3-6)x^2 + (-7+6)x + (-4-1)

-3x^2 – x – 5

# 5 just add up the sides

2x+3x+4x+1+4x+1

13x+2

# 6

(5x^2 – 7x – 6)-(8x^2 + 6x – 1)

(5-8)x^2 + (-7-6)x + (-6+1)

-3x^2 – 13x – 5

# 7 ok

# 8 ok

# 9 the number must be less than 10, so instead of 10*10^7 you want 1 * 10^8.
