Question

Rewrite as a product of two factors: 3 + 18d + 21y​

Answer 1

`\huge { \red{\boxed{ \boxed{ \tt \: 3(1 + 6d + 7y)}}}}`

Explanation:

to understand this

you need to know about:

• factoring

let's solve:

in the following expression

everytime 3 is common

(3×1)+(3×6d)+(3×7d)

therefore if you take 3 from every expression we get

• 3(1+6d+7y)

which is a product of two factors
