Question

for the expression 3ab+2+3b+2a,which of the following is a factor​

Answer 1

factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly.

Answer 2

Answer:

(a+1) (3b+2)

Step-by-step explanation:

3ab+2+3b+2a

take two numbers together, such that in those two numbers, ATLEAST one of the variable/ constant is common, no matter the symbol.

like here, we will take 3ab and 3b together and 2 and 2a together

then apply distributive law of multiplication on each pair of numbers.

=> 3b(a+1) + 2(a+1)

(note- when you cannot see any common factor, then it is 1)

=(a+1) (3b+2)

(only if the numbers in the bracket are common, like here it is a+1, then the factorisation will be correct.)
