Question

factorize (x+1) (x+3) (x+5) (x+7)+16​

Answer 1

(x+1)(x+3)(x+5)(x+7)+16 =(x+1)(x+7)(x+3)(x+5)+16=(x2+8x+7)(x2+8x+15)+16

Let, −4x2+8x+11=0(x+4+5–√)(x+4−5–√)=0

⟹(x+1)(x+3)(x+5)(x+7)+16=(x2+8x+11)(x2+8x+11)(x+1)(x+3)(x+5)(x+7)+16=(x+4+5–√)(x+4−5–√)(x+4+5–√)(x+4−5–√)

Hope this will help you buddy...

Have a beteaous day ahead...
