Question

factorise each of following x²+6x-7​

Answer 1

Answer:

(x+1) (x+7)

Step-by-step explanation:

x²+6x-7

bro first divide the last term so that the multiplication of it must be equal to the the term and when upon adding you must get the middle term.

x²+7x-1x-7

now split the term

you get

x(x+7)1(x+7)

you get

(x+1)(x+7)

Answer 2

hence, after factotisaction x^2+6x-7=(x+7)(x-1)
