I've tried doing 3(a+4b)(a-4b), but that doesn't work. Notice it not only says "factorise", but it says "factorise completely".

I did a really tough workout with my arms about 3 days ago. It included push-ups, dumbells, and pull-ups. I worked until my muscles were completed exhausted. It was really the first time I've worked out in about a month or two.

Now I know muscles are built by tearing down tissue and letting your body rebuild them. You're supposed to wait like 3-5 days. I'm getting a bit concerned though because it's almost the 4th day and I'm still having a lot of pain. I can't really extend my arms fully without much pain and sometimes I have trouble sleeping.

Did I work too hard and pull a muscle or did I just get a good workout and my body is still recovering from the stress?

In Shorthorn cattle, both red coat color and white coat color are true breeding. Crosses of red X white produce progeny that are uniformly reddish brown but thickly sprinkled with white hairs; this tpe of coat color is called "roan". Crosses of roan X roan produce 1/4 red: 1/2 roan: 1/4 white. What kind of genetic hypothesis can explain these data?

Scarlet is a recessive mutant in fruit flies (Drosophila melanogaster) with an orange eye color. You have a wild-type fly that you suspect may be heterozygous for scarlet. If the mutant allele is st and the wild-type allele is st+, what cross would you make to determine if your fly was st/st+ or st+/st+? Predict the results of this cross.
