Question

solve by factorization x=72/x+1
​

Answer 1

Step-by-step explanation:

transposing x+1

x²+x-72

x²-8x+9x-72

x(x-8) + 9(x-8)

(x+9)(x-8)

x can either be -9 or 8

Answer 2

Answer:

=> x2-x-72

=> x2-9x+8x-72

=> x(x-9)+8(x-9)

=> (x+8)(x-9)

=> x+8=0 x-9=0

x=9 ans.

=> x=-8 it is not possible.
