1. x²+5x+4

x²+5x+42. x²-7x+0

x²-7x+03. x²+2x+1

x²+2x+14. x²-6x+5

x²-6x+55. x²-11x+10

Answer:

F - First terms

O - Outer terms

I - Inner terms

L - Last terms

1. (x + 4) (x + 1)

= (x)(x)

= (x)(1)

= (4)(x)

= (4)(1)

= x^2 + x + 4x + 4

= x^2 + 5x + 4

Then use this as a guide for the other numbers.
