Hello, Im new to factoring polynomials:
6st + 15t -10s -25
(6st + 15t) + (-10s -25) <-- Grouped polynomials
Common factors of both groups:
(6st + 15t) --> 3t
(-10s -25) --> -5
Now factor out the common factor from each group:
= 3t(2s + 5) -5(2s + 5)
The common factor is the binomials but what are the steps to factoring this out? I lost here.
Thank you for clearing that up for me, I appreciate you taking the time to respond.
In closing... When factoring, if I have "opposites" like a - b , how is -(a - b) its opposite? My text says these values are opposites, but it assumes I already know why they are opposites.
The opposite of a value is defined as being the negative of the value. In other words, the opposite of 5 is -5. The opposite of -4 is 4, and so on. If a variable represents a value, then the opposite of x would be -x. The opposite of (a - b) would be -(a - b).
If you think of a value as being a certain distance from zero on the number line, it's opposite would be the same distance from zero going in the opposite direction.
