Factorize: y2 – 6y – 135 – InterviewSolution

1.	Factorize: y2 – 6y – 135
Answer» Given; y² – 6y – 135 Now first find the numbers whose Sum = - 6 and Product = - 135 Required numbers are 15 and 9, So we get; y² – 6y – 135 = y² – 15y + 9y – 135 = y(y – 15) + 9(y – 15) = (y – 15)(y + 9)

Factorize: y2 – 6y – 135

Answer»

Given;

y² – 6y – 135

Now first find the numbers whose

Sum = - 6 and

Product = - 135

Required numbers are 15 and 9,

So we get;

y² – 6y – 135

= y² – 15y + 9y – 135

= y(y – 15) + 9(y – 15)

= (y – 15)(y + 9)
