Answer:

question 11 = (x + 4)^2

question 12 = 3x(x+1)^2

Step-by-step explanation:

question 11

x^2+8x+16

x^2 + 4x + 4x + 16

x(x+4) + 4(x+4)

(x+4)(x+4)

(x+4)^2

question 12

3x^3 + 6x^2 + 3x

3x(x^2 + 2x + 1)

3x(x^2 + x + x + 1)

3x(x^2 + 1x + x +1)

3x(x(x+1) + x +1)

3x(x(x+1) +1 (x+1))

3x(x+1)(x+1)

3x(x+1)^2
