Which expression is equivalent to 7a2b + 10a2b2 + 14a2b3?
2 answers:
Answer:
a²b(7 + 10b +14b²)
Step-by-step explanation:
To find out equivalent expression we need to factor the given expression
To factor it first we find out GCF(greatest common factor)
7 a^2b -------> 7*a*a*b
10a^2b^2 ----->5*2 * a*a*b*b
14a^2b^3 -------> 7*2 *a*a*b*b*b
To get GCF we look at the factors that are in common
GCF = a*a*b that is a^2b
We factor out GCF a^2b, write a^2b outside and divide all the terms by a^2b
7+10b+14b^2 cannot be factor . its prime
The given expression can be simplified in many ways by grouping like terms. The simplest form is obtained by factoring out a²b which gives us the following expression. a²b(7 + 10b +14b²)
