Step-by-step explanation:
Factor the expression by grouping. First, the expression needs to be rewritten . To find a and b, set up a system to be solved.
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 36.
1,36
2,18
3,12
4,9
6,6
Calculate the sum for each pair.
1 + 36 = 37
2 + 18 = 20
3 + 12 = 15
4 + 9 = 13
6 + 6 = 12
The solution is the pair that gives sum 12.
a=6
b=6
Rewrite as
Factor out 2x in the first and 3 in the second group.
Factor out the common term 2x + 3 by using the distributive property.
Rewrite as a binomial square.
