Answer:
=(x-3)(x+7)
Step-by-step explanation:
To factor the trimonial:
, we follow these steps:
Step 1: Multiply the first and last term

Step 2: List out product factors of the term derived above

Step 3: Determine which of the factors sum up to the middle term 4x
The required product is: -3 and 7
Therefore: -3x+7x=4x
Step 4: Replace the middle term by the expression derived in step 3 and factorize.

It = 16x because 13 plus 3 is 16 so its 16x !!!
