Factorize: x2 – 5x – 24 – InterviewSolution

1.	Factorize: x2 – 5x – 24
Answer» x² – 5x – 24 Now, first we have to find out the numbers whose Sum = - 5 and Product = - 24 The numbers are - 8 and 3, So, x² – 5x – 24 = x² – 8x + 3x – 24 = x(x – 8) + 3(x – 8) = (x – 8)(x + 3)

Factorize: x2 – 5x – 24

Answer»

x² – 5x – 24

Now, first we have to find out the numbers whose

Sum = - 5 and

Product = - 24

The numbers are - 8 and 3,

So,

x² – 5x – 24

= x² – 8x + 3x – 24

= x(x – 8) + 3(x – 8)

= (x – 8)(x + 3)
