HOW TO FIND THE MISSING FACTOR OF A POLYNOMIAL

Find the missing factor :

Problem 1 :

4 × ? = 8x

Solution :

4 × ?

= 4 × 2x

= 8x

So, the missing factor is 2x.

Problem 2 :

5 × ? = 15y

Solution :

5 × ?

= 5 × 3y

= 15y

So, the missing factor is 3y.

Problem 3 :

3 × ? = 9a²

Solution :

3 × ?

= 3 × 3a²

= 9a²

So, the missing factor is 3a².

Problem 4 :

3x² × ? = 12x²

Solution :

3x² × ?

= 3x² × 4

= 12x²

So, the missing factor is 4.

Problem 5 :

? × 7y = 7y²

Solution :

? × 7y

= y × 7y

= 7y²

So, the missing factor is y.

Problem 6 :

? × 2a = -8a

Solution :

? × 2a

= -4 × 2a

= -8a

So, the missing factor is -4.

Problem 7 :

p × ? = -pq

Solution :

p × ?

= p × -q

= -pq

So, the missing factor is -q.

Problem 8 :

? × 3a = 6a³

Solution :

? × 3a

= 2a² × 3a

= 6a³

So, the missing factor is 2a².

Problem 9 :

8s × ? = -24st

Solution :

8s × ?

= 8s × -3t

= -24st

So, the missing factor is -3t.
