Question

factorise the following expressions a²+8a+16​

Answer 1

Answer:

a^2+8a+16

=> a^2+(2×a+4)+4^2

=> a^2+4^2+(2×a×4)

=> Using (x+y)^2= xy+y^2+2xy

Here,x=a and y=4

=> (a+4)^2

Step-by-step explanation:

Answer 2

Answer:

a²+ 8a + 16

=> (a)² + 8a + (4)²

This expression is in the form of x² + 2xy + y², where:

x = a , y = 4

x² + 2xy + y² = (x + y)²

a²+ 8a + 16 = (a + 4)²
