Question

The factorisation of x2+8x+16is​

Answer 1

Answer:

x^2 + 8x + 16 = (x+4) ( x+4)

Step-by-step explanation:

x^2 + 8x + 16

= x^2 + 4x + 4x + 16

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

= (x+4) (x+4)

OR x^2 + 8x + 16

= x^2 +2× x × 4 + 4^2

= (x+4)^2

= (x+4) (x+4)

Answer 2

Step-by-step explanation:

Answer:

x^2 + 8x + 16 = (x+4) ( x+4)

Step-by-step explanation:

x^2 + 8x + 16

= x^2 + 4x + 4x + 16

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

= (x+4) (x+4)

OR x^2 + 8x + 16

= x^2 +2× x × 4 + 4^2

= (x+4)^2

= (x+4) (x+4)
