Question 1153434


Which of the following is the factored form of the polynomial expression 


your expression: {{{x^2-6x-7 }}}

to factor it, first form two groups with two terms each

{{{x^2-6x-7 }}}-> to form groups, write {{{-6x}}} as {{{x-7x}}}

{{{x^2+x-7x-7 }}}-> group first two terms and second two term together 

{{{(x^2+x)-(7x+7 )}}}......factor out {{{x}}} from the first group, and {{{7}}} from the second group

{{{x(x+1)-7(x+1 )}}}

{{{(x+1 )(x-7)}}}-> your answer
