Hey there,
The first step in solving this problem would have to be to add the two binomials together:
Knowing this now we find the GCF which would have to be 2x which goes into both terms.
The factored form would have to be 2x(5x - 2).
The GCF is 2x and the factored form is 2x(5x - 2).
Hope I helped,

Answer:
3a^2 + 20a + 34
Step-by-step explanation:
(2a + 5)^2 = 4a^2 + 20a + 25
(a +3)(a - 3) = a^2 - 9
Put these two partial answers together.
4a^2 + 20a + 25 -(a^2 -9 ) Remove the brackets.
4a^2 + 20a + 25 - a^2 + 9
4a^2 + 20a + 25 - a^2 + 9
3a^2 + 20a + 34
