Question

Solve and explain please ^u^
Factoring trinomials:
2s(squared) + 5s + 3 = ?

Answer 1

factoring by grouping means we split up the middle term in a certain way
it is hard to explain and easier to see if you watch carefully\[2s^2+5s+3=2s^2+2s+3s+3\]notice the way I split up the middle term we can now factor a 2s out of the first two terms, and a 3 on the next two:\[2s^2+2s+3s+3=2s(s+1)+3(s+1)\]and alost by magic now we can factor out s+1 from the above and get\[2s(s+1)+3(s+1)=(2s+3)(s+1)\]and that is factoring by grouping

Answer 2

2s^2 + 5s + 3
(s + 1) (2s + 3) = 0
=> s = -1, s = -3/2

Answer 3

though we are not told that it equals zero...

Answer 4

I thought the question is solve, so I assume solve for x :)
