Answer:
Step-by-step explanation:
Split the middle term into two terms:x²-7x+x-7=0
Factor the first two terms and the last two terms separately:x(x-7)+(x-7)=0
Factor out:(x-7)(x+1)=0
Apply Zero Product Property:x-7=0 or x+1=0
Rearrange unknown terms to the left side of the equation:x=7
Rearrange unknown terms to the left side of the equation:x=-1
Combine the results:x=7 or x=-1
answer: x=7 or x=-1
