Factorize: p2 – 4p – 77 – InterviewSolution

1.	Factorize: p2 – 4p – 77
Answer» p² – 4p – 77 Now, first we have to find out the numbers whose Sum = - 4 and Product = - 77 The numbers are 11 and 7, So, p² – 4p – 77 = p² – 11p + 7p – 77 = p(p – 11) + 7(p – 11) = (p – 11)(p + 7)

Factorize: p2 – 4p – 77

Answer»

p² – 4p – 77

Now, first we have to find out the numbers whose

Sum = - 4 and

Product = - 77

The numbers are 11 and 7,

So,

p² – 4p – 77

= p² – 11p + 7p – 77

= p(p – 11) + 7(p – 11)

= (p – 11)(p + 7)
