Question

solve this with steps​

Answer 1

area of rectangle = l x b = x² + 8x + 12

                             => l x b = x² + 2x + 6x + 12

                           => l x b = x(x+2) + 6(x+2)

                           => l x b = (x+6)(x+2)

∴ As breadth is not given we can assume the length to be either (x+6) or (x+2).

Answer 2

$\huge\frak\red{Answer}$

x²+8x+12

→x²+2x+6x+12

→X(x+2)+6(x+2)

→(x+6)(x+2)

→X = -6 or x= -2
