Question

7(x-1)+x(1-x) factorise this equation​

Answer 1

Answer:

(7+X) (X-1)

7+X=0

X-1=0

X=-7

X= 1

THEREFORE X= 1, - 7

Answer 2

Step-by-step explanation:

7x - 7 + x - x^2 = 0

-> -x^2 + 8x - 7 = 0

-> x^2 - 8x + 7 = 0

-> x^2 - 7x - x + 7 = 0

-> x( x - 7 ) - 1( x - 7) = 0

-> ( x - 1) ( x - 7 ) = 0

Therefore, x = 1 or x = 7
