factorise the above​

Answer 1

HEYA ❤️

Here's your answer !!

By splitting middle term,

x²+7x+6

product=6

sum=7

hence,

x²+6x+x+6

x(x+6)+1(x+6)

(x+6)(x+1) [required factors]

Hope it helps !!

Answer 2

${x}^{3} + 7x + 6 \\ \\ {x}^{3} + x + 6x + 6\\ \\ x( {x}^{2} + 1) + 6(x + 1) \\ \\ ({x}^{2} + 1)(x + 1)$
