Question

x2+25x144 factorise need answer

Answer 1

Answer:

( x + 16 )( x + 9)

Step-by-step explanation:

Using splitting middle term method

find two numbers "a" and "b" . Likewise a*b should be 144 and a + b should be 25

The two numbers are 16 and 9

16*9 = 144 and 16 + 9 = 25

Now substitute it

x² + 16x + 9x + 144

x ( x + 16 ) 9 ( x + 16 )

( x + 16 )( x + 9) is the answer

I am sure that this answer is correct

Hope my answer helps you
