Answer 2

EXPLANATION

Question

1) x^2 + 2x + 1

using middle term split to factorise

x^2 + x + x + 1 = 0

x ( x + 1 ) + 1 ( x + 1 ) = 0

(x + 1 ) ^2 = 0

2) x^2 + 5x + 4

x^2 + 4x + x + 4 = 0

x ( x + 4 ) + 1 (x + 4) = 0

(x + 1 ) (x + 4) = 0

x = -1 and x = -4

3) x^2 + 12x + 36

x^2 + 6x + 6x + 36 = 0

x ( x + 6 ) + 6 ( x + 6) = 0

( x + 6 ) (x + 6 ) = 0

(x + 6 ) ^2 = 0
