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.
Answer:
a = kb
Step-by-step explanation:
"a is directly proportional to b" is expressed as a = kb, where k is the "constant of proportionality."
ANSWER
