    Sure! Although explaining one will do the rest. For the first one, you find a common factor between all of the coefficients which was 2. I divided 2 out of all the coefficients leaving me with x2+5x+4. To find the simplified form, you use 5 and 4. The two numbers after the x in the solution must add up to 5 and be factors of 4. 4*1=4 and 4+1=5 so the solution was 2(x+4)(x+1). Does this help??

    Here are the general steps: what is the product of a* c? what are the factors of (a*c) that add up to b? pay attention to the signs rewrite b with the 2 terms regroup the original into 2 sets of 2 terms each and each group use the distributive property and rewrite with the common factor
