Question

$\sqrt{7} x^{2} -6x-13\sqrt{7}$

Answer 1

= √7x² – 6x – 13√7

= √7x² – 13x + 7x – 13√7

= x ( √7x – 13 ) + √7 ( √7x – 13 )

= ( x + √7 ) ( √7x – 13 )

Answer 2

Answer:

Step-by-step explanation:

= √7x² – 6x – 13√7

= √7x² – 13x + 7x – 13√7

= x ( √7x – 13 ) + √7 ( √7x – 13 )

= ( x + √7 ) ( √7x – 13 )
