When multiplying two binomial expressions.
we need to use the foil system in math.
-FOIL Method -Special Products -Geometry It's depends on you :)
When you get a problem like this. x2+xb+xb+b Example: 49+21+28+12 = (7+3)(7+4) or (-7-3)(-7-4)
It is only not needed if you know of another method. If FOIL is the only way you know to multiply two binomials, then it is definitely needed.
You use it in math, especially in algebra 1. The F.O.I.L method is like the distributive property basically.
luster is i do not know
No. Math is relative to you, your location and frame of reference. Our math is limited to what we understand and can compute. Math is greater than what we know, or can know.
Writers do not need to know math to succeed.
I know that it sucks...
To answer this one would need to know the width of the length of foil in question.
What math test is it? I need to know to answer.
well, i know that aluminum foil has aluminum in it.
