Answer:

(a) (x+3) (x+9)

(b) (x+4) (x-4)

(c) (x-4i) (x+4i)

(d) (-2+i) (-2-i)      

Step-by-step explanation:

We have given the quadratic expressions and we have to write these expressions in factor form

(a) x^2+12x+27

It can be written as x^2+9x+3x+27

x(x+9)+3(x+9)

Now taking (x+9) as common

(x+9)(x+3)

(b) x^2-16

We know the algebraic equation a^2-b^2=(a+b)(a-b)

x^2-16=x^2-4^2=(x+4)(x-4)

(c) x^2+16=(x-4i)(x+4i)

(d) x^2+4x+5

It can be written as (-2+i)(-2-i)
