Question

factorise xto the powerof2+14x+49

Answer 1

${x}^{2} + 14x + 49$
${x}^{2} + 7x + 7x + 49$
$x(x + 7) + 7(x + 7)$

$(x + 7)(x + 7)$
therefore x =( -7)


it's best answer and correct also.

Answer 2

Hey there!.

______________________

x² + 14x + 49

On splitting the middle term..

x² + 14x + 49

=> x² + 7x + 7x + 49

Taking common..

=> x² + 7x + 7x + 49

=> x (x + 7) + 7 (x + 7)

=> (x + 7) (x + 7)

It can also be written as :

$\bold{(x + 7) {}^{2} }$
